Adding more outputs to a OEM J30 alarm

[Infinitiguy19]

I have a 1993 Infiniti Q45 with no keyless entry, I am in the process of adding a OEM J30 Keyless entry system. I am doing that to keep the car as OEM as possible.

But what saddens me is that I won't be able to do all that I could with a after market system. So is there any way to make it so I can control the windows with the second lock pulse and the third and forth unlock pulse? There is only one lock pulse and two unlock pulses for drivers door priority unlock.

Basically I would like to lock all the doors with one button push, close all the windows (4) with a second lock push. I would like to unlock the drivers door with one button push, unlock all the doors with a second push, unlock the two front windows with a third push, and open the back windows with a forth push of the unlock button.

Yes I know I need two DEI 530T's (Or similar) to do what I want.

I've never seen anything like that. What's the aversion to an aftermarket unit? They tend to do more, and could do what you are looking for (for the most part at least).

Well I don't like after market alarms because they don't look right, remote wise. I guess I am used to going to a used car dealership and seeing so many after market remotes... Plus with a after market system you have more wiring problems to deal with because you entrust someone to do it.

But opinions aside I am using a OEM system to prove to people that you can have the best of both worlds as far as getting a OEM system on a 1992-1993 Q45. I am trying to see if its possible to get this to work on a 1990-1991 Q45 but the door lock timers are not even close.

But I plan on spending 1 day in labor (My self) and $50 shipped to my door. And in the end I will have a very clean install with lots of pictures, wiring diagrams and maybe even video's to fall back on for trouble shooting support.

Now I am just looking for a way to have the first two unlock pulses ignored by a control module. I have found a way to get the windows to go up though.

Thanks for the reply so far.

I'm not sure how much you know about electronics, but I'd venture to guess that you could use some relays or transistors with the appropriate caps, resistors, and diodes to make a latched ladder control scheme to make it work.

[Infinitiguy19]

Hey your in Boston right?

If so want to meet up and I will explain what I mean, show you what I have done so far....If your interested email me.

But I am not very good with electronics. I only know the basics like wiring alarms, tweeters...the simple stuff. But do you mind going into further detail about what you mean?

I will be pretty impressed if you get this thing to work as it is OEM, let alone adding features to the stock system.

the thing that concerns me is what kind of signal the remote is sending, and what kind of signal the car is expecting to see. my guess is you'd need to modify the remote and the receiver, not just the receiver..

You'd probably be better off to design and program your own receiver than you would be to somehow "count" the number of times you pressed the unlock button. Also, theres another button on the remotes for illuminating the interior, that you might be able to reroute its function to something else..

Lets say this:1. You press the lock button once, and that locks all doors (stock)2. Press and hold the lock button, and it rolls up all the windows (replacing the function where it activates the car alarm)3. Press the unlock button once, and it unlocks the drivers door (stock)4. press the unlock button twice, and it unlocks all doors (stock)5. Press and hold the unlock button, and it rolls down the front windows (stock)6. press the "illuminate button", and it rolls down the back windows.

I think replacing functions is going to be a much easier approach, but by far the first thing you need to do is get it working in an as-designed fashion FIRST.

BTW, if you think you can pull this whole thing off in 1 day, from ripping apart the interior, doing all the wiring, and putting it all back together, you are on crack....

I would say the hardest part about this is: Running a wire from the trunk to the battery, getting the Anti-Theft Control Unit out (Thats a tough mofo) and maybe the door switches.

I will let you know that the ignition will not need to be touched but keep that to your self till I finish this and let everyone know.

Do you think if the unlock button is held down the receiver would recognize that let alone the after market window control modules?

I don't want to tie into the dome light output because it won't look good, I am a very dedicated guy (My car and GF could attest to that).

I count one day as in dusk to dawn so there are some things certain, Advil stocks will go up as will Budweiser.



But in all seriousness the alarm will work 100% from a J30 to a 92-93 Q45, But 90-91 is uncertain but I would not mind spending more time to investigate further. After all I did spend countless hours on this and put my GF's Patience to the test.

I'm going to put a little more thought and head scratching into this and see what I can think of. I think I could come up with something to make this work in the way that you are thinking. Maybe at some point we can meet up and do something.

[Infinitiguy19]

Yeah man sounds like a plan and thanks for the help so far.

[Infinitiguy19]

Hey The Converted I don't need a way to close the windows with these modules, I just need a way to open the windows. Do you think they could be opened like this: http://www.p71interceptor.com/...1.jpg

Would it be too much to ask for fuel lid/door control?

[the converted]

So you just want the windows to roll up when you arm the alarm, and all 4 to go down with the press of a button? I think that I figured out how to build the circuit, I just want to be sure of what you want before I really sit down to figure it out.

[Infinitiguy19]

Not really, Here is what I want 100%:

When the doors a locked by means of the lock button with one press of the button the doors lock, no modification needed.

When the lock button is held for 1.5 seconds or more the ALL the windows and sun roof closes, A negative output is required for this to interface with the two 530T's and the single 529T.

When the unlock button is pressed ONCE the drivers door is unlocked, No modification needed.

When the unlock button is pressed a second time ALL the doors unlock, No modification is needed.

When the unlock is pressed a third time all the windows open up.

OR if possible make is so the third press will only open the front windows, forth press will open the rear windows.

Now the venting feature would be nice but if not I am sure the same thing could be accomplished by holding down the lock button so I can close the windows till I get to a good spot.

And if possible:

One press of the trunk button the trunk opens, No modification needed.

Press and hold the trunk release button for 1.5 seconds the fuel lid door opens. If this is possible it would be great if not so what.

I think that it might be possible to set it up like that. I'd need to play with the alarm and test the outputs to see exactly how it behaves when you hold a button on the remote down though.

[Infinitiguy19]

Hey I hear you, But this won't be set up till it warms up outside. Garage FAIL

But I can tell you that the "Panic" output give a 0V-12V-0V-12V....(Positive output) for 30 seconds. Thats needed to make the horn and light blinking on and off. So a steady output would be needed, that could be made by means of a relay like this: http://www.the12volt.com/relays/page5.asp#lsp

And converting the positive to a negative output: http://www.the12volt.com/relays/page1.asp.

Do you think you can make more of these boards for any other J30 or 9-93 Q45 owners?

[the converted]

Once it is up and running, it shouldn't be any issue to make them for other people. If your not going to be installing it until the spring, I can power it up on a bench up here and do some testing.

[Infinitiguy19]

Well call me up next week when I have it in my hands. I am waiting for the guy I bought it off of to ship it to me.

[Infinitiguy19]

Hey I just got the keyless entry stuff in....

[the converted]

Cool. I'm traveling until the 1st, so we should work something out for after that.

[the converted]

Paul, I'm back and you have mail.
