Installing a 1994-1997 J30 Keyless entry alarm on a 1992-1993 Q45

[Infinitiguy19]

Is it possible to interface a J30 alarm onto a 1990-1993 Q45?

That is what I want to answer soon because I can tell my door locks hate me or my key.

I am looking over and compaing the wirring diagrams between 1994 J30 and a 1994 Q45. I will look at the 1993 Q45 wirring diagram for the theft system tommorow but so far so good.

The J30 has no BCM (Body Control Module) which controls all of the interior functions and some exterior ones as well. and the 1994-1996 J30 never had the "Hold unlock to open front windows feature" but thats alright.

To add the G20 and J30 share the same alarm system as far as the wiring diagram goes.

So my questions:

Can the OEM Q45, J30 and G20 alarm be made to open and close the sun roof and all four windows maybe the fuel door but that may be pushing it on the lock and unlock button?

Would I have to cut into the OEM harness or can I cut into sub harneses that are easily replaceable?

Would I only need the remote and computer for the keyless entry? I say yes but I am unsure.

Also where is the antenna located on the J30 and G20? Is it the antenna mounted on the rear glass or is it somewhere else??

One if not only true reason for this is because I dislike aftermarket remotes. Not the alarms because you can't see the wiring but the remotes.

Yet another tough desion I face is to keep to my orignal plan about the Nissan president power folding mirrors or not. My orignal plan was to have them open and close with the seat and the steering wheel (Automatic Driver Postioner). I thought that because I feel it makes the feel more alive.

So have the mirrors work with ADP or Keyless entry, that is the question.

like they always say, if theres a will theres a way...

its not gonna be a plug and play situation especially if you want to try and make it do stuff it doesnt already do.

Id be pretty impressed if you could get everything to work properly with a stock J30 remote system...

[Victor]

The J30 power door locks are a known problem area too. Do a search on the J30 forum and you will see many threads concerning the problem. As for the J30 alarm system, I wish I knew how to disable it, it just annoys me going off when I don't want it to. If you have theft insurance who cares if someone steals your car.

[yodawill2000]

I would care if I was out of town !!!

[Rex]

Any thought to just pulling the ignition, locks and keys off a car without any "sticky key" issues? Probably about the same $$'s and less electronic/diagnostic inventing.

[Infinitiguy19]

I have some GREAT news and some sad news:

The great news is that the J30 alarm will fit without problem and I am 99.9999% sure.

The sad news is that the window and sunroof working with the lock and unlock button is a little ahead of me do I may not do that just yet.

But I also have some questions:

The #13 pin on the theft control unit is used on the 1990-1993 Q45 control unit, yet there is no color associated to it in the service manual. The J30 theft control unit doesn't use the #13 pin.

So would the above pose a problem?

I also found out that the antenna used on the OEM G50, JPY32 (J30) and P11? (G20) is the back window antenna shared by the radio.

So I believe I saw Wes say somewhere that he "Cut the keyless entry antenna" when he did the fuel pump. Well that's not the case unless he cut the window antenna.

And this will be my BIGGEST project to date, Seriously the Wiring diagram makes it seem simple compared to what it is.

Also the J30 keyless entry system seem to use Diode and I am not sure why, is there a way to get rid of them?

So to sum it up: 1990-1993 Q45 can have keyless entry but not OEM way to control the sunroof and windows.

Also I forgot to add that ONLY 1992*-1997 Keyless entry control units with matching remotes will work on the 1990-1993 Q45, Sorry for the confusion.

*The 1992 J30 was introduced to Canada.

Why not just get an aftermarket alarm system,even one with remote engine starting installed??????

[Infinitiguy19]

That would just kill half the purpose of this idea.

Like I said I don't like aftermarket car alarms/car starters. Plus how many 1990-1993 Q45's have you seen with an OEM keyless entry alarm?

IF and thats a big if I could find a aftermarket alarm/car starter that would work with the OEM remote I may go with that. But I have a better chance of installing the J30 Keyless entry than finding such alarm.

[paranoidjack]

I admire the effort, but have to side with qship and think you could probably spend your time elsewhere for more bang for the buck. But props for the effort and best of luck; I'm sure that could get hairy quick.

[elwesso]

honestly i think that hacking up the harness to make a factory system retrofit in would probably screw things up far more than attempting to install an aftermarket one, IMO.

You can successfully install an aftermarket keyless setup with a good installer, just many times its not good.

[Infinitiguy19]

Thanks for the advise, But I know when to quite like in the case of the power headrests.

But in this case everything either matches up or is'nt used between the two systems. All but #11 pin on the J30 anti theft computer, And that is for the unlocked signal.

But like everything else this will be done or scrapped.

[qship96]

Even if it all goes as planned you end up with a antiquated half-a** security system compared to whats available in todays aftermarket product line.....for a few hundred dollars a viper system will not only provide similar features to the factory system, but add motion sensors,glass break detection,1 mile paging to notify of attempted break-in,remote start,remote window/sunroof control and many other desirable features unavailable from the factory system


The factory system is BASIC at best.....it wont even go off if someone smashes a window to steal your stereo/radar detector/etc....or go off if someone hits the car or jacks it up to steal your wheels.....hardly worth anything in reality.

[Infinitiguy19]

Why do you keep bringing my idea down?

I know all the new systems can do all that, that's fine and dandy. If you search you will see I made a topic asking what the best car alarm/start is or was in that time.

The other reason behind this is for cost sake, I plan to do this for no more than $50 total (Labor* and parts).

And I am worried about my car trust me but if I was to be to worried then I would put a titanium bubble around my car.

But what do you have for a car alarm?

And yet another reason why I want to do this:

I want to make a wiring diagram, take video, pictures and what ever else I can do to make troubleshooting easy and help someone else replicate my system.

And I want add one more thing I hope to be able to do with this alarm, I want to be able to press unlock and ONLY unlock the driver door. Then press unlock again and open all the doors.

And if I wanted to make you mad I could say: BG transmission flushes are the way to go and are better than drain and refill.

*tylenol maybe beer depending how bad it is.

[elwesso]

I know you saw my previous reply... Intentional provoking is not to be tolerated.

Play by my rules, or find a new sandbox to play in!

[Infinitiguy19]

All further progress will not be posted.

Nor will there be a write-up on this one fellas.

Thank You. No need to waste bandwidth on unsound projects!

Hello qship96,

As your email is unavailable, I hope that you notice my post here.

Do I recall you as being one the Forum's sound system experts? And making available custom pigtails for adding an MP3 players? If so, I may need one of your pigtails, and help with one question:

My 93 Q45 has the standard radio/cassette player which is failing. I would like to replace it with a CD player. I read where IOS sells an adapter which allows a CD unit from a 94-96 to be retrofitted to a 90-93. Is this correct? What other options might I have to gain CD player capacity short of an entire new aftermarket set-up?

Thanks,
Jim in the mountains of western North Carolina

No, I am not the person who made the pigtails allowing one to connect Ipods/mp3 players.....hopefully someone will chime in and post the correct Nico member who provided those. The easiest way to gain cd playback would be to swap your headunit with one from a later nissan/infiniti that included a cd player{1 disc} as part of the headunit,which would also include jacks allowing you to add a cd changer in the trunk if wanted- this would allow you to retain the bose amps/speakers already in your car.....plug and play as they say.

[elwesso]

Jim, i think you're thinking of Shane, qsiguy...

Hit him up!

[Infinitiguy19]

People like the above poster inspire me to prove them wrong.

Whats the difference if its a aftermarket or OEM alarm, the harness or parts of it need to get cut up right?

Well I am an OEM man and if that mean cutting into the main harness well I just can't do it. What if someday I decide to sell my car to some moron who will never appreciate it as much as me on the Barret Jackson auction? They will want a OEM original car intact. That is why all my modifications are not tied into any main harnesses and can be remove in the same time they were installed in.

I always say that 1994-1996 Q45 guys take there cars for-granted, And if Brian was around I think he would say it would have been easier to buy a 1994. So if I have a OEM 16 year old (2009) keyless entry compared to a cheaply installed aftermarket alarm that is brand new I am happy. Yes I know you think Crappy installer??? Well I dare you to find me a GOOD installer because there are none around here that I trust.

And if they want to break my windows well what difference would a glass break sensor make? Now if you complained about the OEM horn I would agree with you. Because if you add a train horn to the Q as a anti-theft horn I am sure many will think twice before even LOOKING at the Q.

Thank You. No need to waste bandwidth on unsound projects!

The only bandwidth I am USING is a few kilobytes maybe Megabytes at most of NICO's and mine and of course the members who choose to view this topic. But if they choose to view it that's there problem not mine. But if you can't spare any bandwidth on your connection I suggest you move from dial-up and choose a broadband connection. Or just don't view this topic at all because I haven't heard anything from you that I already know from you.

So please do me a favor and think before you speak because clearly this isn't the case here. And its people like you that make NICO not worth being on, at least in my opinion.

Now what you all have been waiting for:

1992-1993 Q45's can have the OEM J30 alarm integrated in because of there door lock timer and its connections. The 1992-1993 Q45 have the same connections for the door lock timer as the 1993-1997 J30.

Pin #9 on the anti-theft module had me all tied up because that was what the OEM alarm disarm is. Now pin #9 is used already by the Q45 anti-theft module. I thought about making a harness and what not to swap the pins...But that's not needed. All that is needed is a cancel wire to the Multi-control unit from the OEM Q45 anti-theft module.

And the door lock timer is needed from a J30 as well because of the two extra pins for the lock and unlock from the remote.

And the absolute hardest part will be tapping into the ignition switch with out messing anything up and of course making it look factory. I saw a post by Robert Bowden (RobertsnewQ) about how difficult it was to do so I will obviously leave that to a professional.

But other than the above the hardest part so far was looking over the wiring diagrams multiple times (Actually since I started this topic till today I have looked at them) and getting different color wire preferably the same as stated in the service manual.

But like I said so far so good.

O yeah the service manual for the 1990-1993 Q45 maybe 1994-1996 Q45 looks like it was put together by some stupid minimum wage monkeys. And I say that after looking at the Anti-theft section alone multiple times. For one the colors are listed completly...I feell bad for newbie techs or anyone else given the service manual to diagnose a Q.

And the parts that are needed for this project:

Color coded wire preferably matching the service manual colors.
J30 door lock timer (Would be wise to re-solder it before installing to prevent and problems)
J30 Multi-control unit
Matching keyless entry remote

Optional:

Friend(s)
Beer
Pizza
Tylenol
Girls?

[goody90q45]

Don't take the criticisms too harshly. It's an internet forum and it's easy to dish out flack when you're thousands of miles away. Most of us, including the critics, probably wish we lived closer so we could come help with the install and make it work.

Godspeed.

[Victor]

Around here false alarm car alarms going off are so common that no one even pays any attention to car alarms anymore other than getting annoyed and getting tempted to go rip the car alarm or battery out of the offending car. I think anyone whose car alarm sounds for more than one minute should be subject to a fine or having his car towed.

[Infinitiguy19]

I forgot to mention that I am somewhat sure that the windows up and sunroof closed with the lock and unlock button and vise versa can be done. I say that because the J30 keyless entry has 2 outputs for the door lock timer to lock and unlock them. Now if I can tie into them I am sure it MIGHT work.

And to also add that it may seem impossible for the 1990-1991 Q45 people to add this to there car but clearly I have proven nothing is impossible, It just takes some work. But if anyone is interested let me know because I would be glad to help as much as possible.

So now to install this and move on to my next modification what ever that may be.

And a question to the 1994 Q45, J30 and G20 and below that year: Does your keyless entry remote have a buzzer and if so does it make any differnce?

And someone from the NICO staff please change title to: Installing a 1994-1997 J30 Keyless entry alarm on a 1992-1993 Q45

[elwesso]

FYI you can take the pins out of the harness connector and just switch them with the wires on it..

Just go for the switcheroo.

[Infinitiguy19]

I did'nt think of that, Thanks.

I still need to know what is the OEM alarm disarm color wire and pin if possible?

And I think I can use the 530T and 529T for the sunroof. But when its raining or snowing and I press the unlock button I assume the windows will open because they are wired into the lock and unlock signal given by the multi-control unit. So if there is a way to make it so the unlock and lock button have to be pressed a second time or third time to prevent any snow or rain from getting it would be nice.

But other than that the alarm looks good on paper and the only change needed is to wire the OEM alarm disarm to the correct wire instead of #9 pin like on the J30.

Now the fun part, getting the parts and installing some and having trusted others do the rest.

[Q451990]

Nissan's "typical" way of rolling the windows down with the remote is by having the user press and hold the unlock button... not sure if that was the case on the J30.

The wife's G uses 1 press of the unlock button for the driver's door, 2 presses for the other three doors, and hold it down for several seconds to roll the windows down.

Heath

Right, but the J30 has no factory way of rolling the windows down because of a lack of a LAN system and a Body Control Module of course.

But some more questions I have:

Is there a all in one control unit to control the sunroof and 4 windows?

Where can I get differnt color wire simmilar to OEM?

How do cars with BCM like the 1994-1996 Q45 exactly control the windows?

How do I add a inline fuse that the alarm requires?

[Q451990]

Not sure on the wire... I have never tried to match OEM color code wire for anything. Maybe if you can find a donor car you could chop up some of the huge wiring harness that goes from the front to the back of the car under the seats... Those are probably the longest unbroken run of wires.

There are inline fuse holders available at parts stores. No idea on the other questions...

I was hoping to avoid that.

Heath

Totally forgot about that.

And from my understanding the "Panic" feature of the keyless alarm is triggered by holding the lock button for a little more than 1.5 seconds. So if I want to use the "Lock" button to roll up the windows and close the sun roof I have to not be able to use the panic function. And really does anyone really use the panic function?

But shane or any other car audio/alarm specialist please help.

[Infinitiguy19]

Can the car phone antenna be used as a antenna for the keyless entry along with the radio antenna mounted on the rear window?

Do any of the 1994 Q45 remotes have buzzers, if you have one is it worth it over a remote without one?

Is there a way to add two more outputs to the OEM J30 alarm?
