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

[Infinitiguy19]

Also what bugs me is why there is a relay for the rear door switches:

Is it really needed because I doubt it. I think its needed for something else.

[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?

Still unsure on this one.

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

Still unsure on this one as well but I plan to add my own buzzer to the OEM remote.

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

I am working with another NICO member on this and so far it seems promising.

This is unneeded so thats good.

Here is a spoiler:

1992-1997 J30 keyless entry car alarm on a 1990-1993 Q45

Get:

Keyless enty control unit1 or more key FOBsdoor lock timermulti-remote control unit relay 1 and 2

Notes------------------------------------------------------------------------------------------------------------------------

Can the rear car phone antenna be used for the keyless entry antenna as well?

SB=Q45 alarm disarm when unlocking the doors

OR=Q45 alarm disarm when unlocking trunk (Temporary alarm disarm)

LG/B=J30 drivers door (for door lock timer)

W=Q45 passenger side (Door lock timer);

11 is lock on Q45

12 is unlock

No need to change small black door lock timer connectors on the Q45, Just solder wires to the door lock timer and add a external connector for them. This is for the lock and unlock signal from the multi remote control unit to the door lock timer.

Pin 18 on Multi-Remote Control Unit is for "Panic" function of key less entry remote. If nothing is connected to it then "Panic" function will be disabled and could be used for something else.

Trunk fuse is always "Hot" but its only a 10 AMP compared to the J30's 15 AMP.

For pin 2 on the Multi-Remote Control Unit, Run a wire from #2 pin to the trunk cancel switch in glove box.

Trunk and door unlock alarm disarm must be separated. Door/disarm unlock is pin #11 Trunk unlock/disarm is pin #10. The trunk/door disarm from pin 20 on the Multi-Remote Control unit needs to be branched off into two wires, 1 for the the trunk disarm/unlock and 1 for the door disarm/unlock

Use the Key switch pin for the Multi-Remote Contol Unit Input for the Key Switch.

Pin 6 on door lock timer need to be routed directly to drivers door lock actuator for unlock.

(Possibly) No need to tie into EACH door switch, Just tie into the G/R wire on the dome light.

Wire colors-----------------------------------------------------------------------------------------------------------------

For J30:Window antenna: GreyAnti-theft alarm disarm: WhiteBattery power: GreenKey Switch: Pink and GreenDome light: Green and RedKeyless unlock: Black and PinkKeyless lock: YellowHorn relay: PurpleDome light to fuse: Brown and WhiteMult-remote control unit grounds: Black

Additionals Features-----------------------------------------------------------------------------------------------------

Add puddle lights under the mirrors.

When adding puddle lights make sure they only work when the car is unlocked and when the dome light button on the remote is pressed.--------------------------------------------------------------------------------------------------------------------------------Add power window/sunroof opener and closer to lock and unlock buttons (Respectivly).

When adding the windows and sun roof opener and closer module add the window/sunroof opener wire to the Multi-Remote Control Unit alarm disarm output.

The doors could be locked by the "Panic" AKA pin 18 on the Multi-Remote Control Unit. So that when the "lock" button on the remote is held down for more than 1.5 seconds the windows will all go up or just the front one. When held down again the rear window will come up as well.

[Infinitiguy19]

Just out of curiosity, How many of you 1990-1991 Q45 owners are interested in adding the OEM J30 key less entry system to your car? I ask because I need to justify actually spending time on this because I don't have a 1990-1991 Q45.

And I am yet another step close to this because I just got a DEI 529T brand new from Ebay for $5 to my door.

And I am working with NICO member:"The Converted" to make the window and sun roof control through the OEM J30 remote work.

But yet another sneak peek as I get close to installing this beast. You only need the door lock timer, Multi-Remote Control unit and of course the OEM remote to make the J30 Key less entry work. That comes to a total price of $50, Any more and you tell the seller to keep the stuff.

But again this Key less entry is so easy to install, probably easier than the 1994-1996 Q45 tweeters actually.

More to come soon.

[Infinitiguy19]

I just got the keyless entry stuff in but there is snow on the ground so the project is delayed.

I called up NEC Electronics America, The makers of the Integrated Circuit (IC) for the 1990-1997 J30 and 1990-1993 Q45 Anti-Theft control unit. Basically its part of the brain for the control unit, I got this as a reply:

Dear Paul,

I left you a voicemail on this as well pointing you to the information in this email. First of all, thank you for contacting NEC Electronics America Technical Support.

The two parts you referenced during your conversation with one of our support operators were D7507SCT(A) 453 9046EY006 and DT507SCT(A) 487 9447EY002. There is no DT507SCT, so I believe it is also a D7507SCT(A). The base part number is actually the uPD7507S. The CT indicated the package to be a 28-P-SDIP(10.16mm(400)) insted of the alternative which would have had a suffice of just "C", a 28-P-DIP(15.24mm(600)) package. The (A) means that it is automotive grade.

Unfortunately, all versions of the uPD7507S were discontinued in 1995. The 453 and 487 after the two parts are the ROM codes. These numbers are assigned when a new unique program is programmed into the ROM of the chip, causing it to have unique functions and features. The actual program placed in the ROM is provided to us by the design owner/end customer and is proprietary. Therefore, we cannot tell you the exact difference in function between the two, just that they have different behaviors due to unique programming in the ROM provided by the end customer.

If you have any further concerns or cannot obtain the desired information, please feel free to contact me at [email protected] or (408) 588-6780.

So that means the they use a different software to accommodate the "Cancel signal from the remote" no matter because I found a way around it. I plan to use the trunk and door signal disarm on the OEM Q45 Anti-Theft control unit. And if that doesn't work then I will make an adapter to use the J30 Anti-Theft control unit. But that will most likely not be done because my first method will work.

And there will be no write up on this one, rather this will serve as a "Build" topic.

[Infinitiguy19]

So much for a truly OEM keyless entry system from Infiniti but no surprising. The Integrated Circuit is made by Alpine of Japan.

More info to follow.

Jeez, months, MONTHS, you have been trying to accomplish what can be completed in 1 HOUR at your local car stereo specialist shop..........time is the most valuable asset you have....use it wisely!!!!

Whats wrong with him using his time, to complete the task he has set for himself? Just because you, or others out there dont/wont use his ideas, doesnt mean he should stop creating them. Its a goal, that at first seems impossible, so all the more reason to feel good about your accomplishments when you complete it!

Keep it up Paul!

... i dont know how much room is in the j30 remote. But my buddy just took apart the alarm controler for his 05 civic, and put the guts into an old SNES gamming system control. It works fine, looks trick, and was easy. IS a swap like that possible to fit into the j30 remote?

[qship96]

I guess it depends on what your goal is.....the journey or the end results and benefits????

[Infinitiguy19]

I am sorry I can't complete this in a timely manner, But its 20*F with 30 MPH winds currently and that has'nt changed much for a couple of months now. I don't mean to tease you guys at all but rather keep you informed, I see now that I should have waited till I was completly done.

But I can guaran-damn-tee you that this will be done before summer is over.

Thanks for the kind words. I took apart the remote and it looks pretty tight in there, If you want I can email you pictures till I finish this project.

[qship96]

"30 degrees,30 mph winds".....thats my point!!!! Just imagine pointing your little remote at the beast from the comfort of your toasty kitchen and pressing one button to summons the monster to life....you brave the cold 10 minutes later and step in to a pre-warmed car, windows de-iced with the mechanicals heated to operating temperatures and ready to go!!!!! remote start/keyless entry/security system all in one and professionally installed in a few hours for a few hundred dollars......sounds good to me!!!!!

[Infinitiguy19]

Well I am not worried about my self but rather the car. The plastic breaks real easy in those conditions...

If I wanted a car starter I might be able too hook it up to the dome light output, But thats not really worth it to me.

[Infinitiguy19]

Well I have made great progress on this project and I will be done soon. When its all done I will use the below cover shown on the keyless entry control unit metal case, With a NICO sticker. I am sure anyone else who wants one can get one from Becky or Greg (Some of the current people responsible for NICO). What a better way to show that you installed the J30 keyless entry on a Q or car that didn't have keyless entry than by putting a NICO sticker on there!

I got the above from one of the test J30's (Oh yes they do exist!!!), there is one left but it went to the crusher. Thanks to xr4racer and if you want the location of the other J30 contact that member. If xr4racer doesn't mind me saying this he had 2 test J30's and the Brabham Special Edition Q45. He raced the Brabham Q and the J's and might have some pictures of the Q!!!

And can any Japanese person translate what it says on the Keyless entry control unit shell please?

[Infinitiguy19]

Here is the translation:

To: Nissan jidoushya (car)

At the bottom, that is katakana for Alpine Corporation.

The kanji symbols that are in parenthesis means corporation.

Thanks to Gold Digger!

I have some tough times ahead as I plan to remove th carpet to make this a truly OEM setup. I also plan to use the 1994-1996 Infinti Q45 front speaker connectors, with the correct color wires. Making the wiring harness for the alarm is also tough and somewhat costly but I can guaran(Damn)tee this harness will last many many years.

I also plan on making a tool that will help to remove wires from those big connectors (Defroster switch, TCS switch...)

Sorry to bring this up yet again after all it does seem like I am talking to myself on this one. But for the remote start issue see this product: http://www.thehoffmangroup.com/autoloc/ ... id=eBayATW.

I got a email from Ebay part of there "Daily Deal" thing and the above was on there.

How's that for OEM alarm and remote start!!!

[goody90q45]

Judging by the 1000's of looks at this thread you're not alone, just breaking into uncharted territory and little help is available. The installation should be much easier for you now with the extra info from the installer.

[Infinitiguy19]

Thanks Mike

Here are some sites I found useful:
http://www.offroaders.com/tech/12-volt- ... e-amps.htm
http://www.powerstream.com/Wire_Size.htm
Not sure on this site: http://www.powerstream.com/Wire_Size.htm

And of course the service manual which Nissan could have done a better job on: http://www.nicoclub.com/FSM

The headliner, carpet and basically most of the interior has to come out to make it OEM (wire it under the carpet), so this will make the tweeters look like a walk in the park. I need to get the OEM 1994-1996 Q45 speaker connector to fit along with getting the correct color coded wire for the tweeters.

Damn I still need to do a write up on the tweeters, It never ends with a Q.

[Infinitiguy19]

I am very sorry to bring this up yet again.

1) Their are 3 inputs for the door unlock sensors on the J30 keyless entry control unit. One is for the two back doors, the other is for the driver and the last one is for the front passenger door. Do you think the keyless entry control unit cares if I were to say get the input from a central location where they all meet and have all four inputs going to the three input pins?

http://picasaweb.google.com/lh/photo/dj ... directlink

2) I want to make a OEM like wiring harness with exact colors and stripes. Bu to make that harness will prove very costly and is possibly the most expensive part of this project. So do you think I should continue to make this harness and delay the keyless entry or create a simple multi-colored non OEM color matching harness?

The things I live by when it comes to this car is:

1) Do no harm
2) keep it all OEM

[lino]

I say as long as you do a clean job and make everything work as it should, then don't worry about the little stuff like the colors. Can't wait until this project is completed. Hope it will be soon.

[qship96]

this is becoming a LOOOOOONNNNNNNNGGGGGG term project.......almost a year now.........a year that could have been spent enjoying a professionally installed aftermarket keyless entry/alarm/remote start system.

[Infinitiguy19]

I know Qship I am very sorry you have to put up with this. But I am Lazy and I want it done right which doesn't end well as far as a completion date.

You know what Lino I say the hell with it I am making this wiring harness with simple non liquid electric tape painted strips, Just simple solid colors.

The power wire will still be hard to route to the battery

[Infinitiguy19]

Wow I can't believe its been two years on this project and I have done nothing on it.

For those that want to do this here ya go: https://docs.google.com/Doc?docid=0AZVD ... DR4MnRkYzY

And if that doesn't bring traffic back to the Q45 section of this place NOTHING will!

[qship96]

this is becoming a LOOOOOONNNNNNNNGGGGGG term project.......almost a year now.........a year that could have been spent enjoying a professionally installed aftermarket keyless entry/alarm/remote start system.

See above., I wrote that over a year and a half ago to you!!!!!!!.....you wasted yet another year ++++ without enjoying the benefits you could have easily got following the above advice!!!!!!!

Get yo a** down to the car audio shop and get it done, now!

[Infinitiguy19]

So the secret is out and all I got was one response?! Granted I didn't actually do this to my car yet but my blue prints/research pretty much prove it to be possible to do this.

Well I tried...

Qship like I said I like OEM stuff. I have seen far too many cars with aftermarket remotes on key chains. It looks wrong to me I am sorry. Plus I am a very very patient.
