'89 240sx, Matrix 3.5 alarm/remote start

Hey all,

Trying to install said alarm into my '89 240sx.  Can't figure out how to wire up the manual push button for the remote start (it's the push button that is mounted in your car.  the big one that came in its own bag)  Can anyone tell me specifically which wires to connect to the button and where/how to connect them?  The instructions in the manual were sketchy at best.  Also, would anyone happen to know exactly where to find the door trigger/dome light wire for my car?  I've looked through several wiring charts, and the locations they gave were either very inconvenient (at dome light switch?!?) or vague (behind instrument cluster???).  Does anyone know a good, easy to find and access spot for me to tap in?  Thanks in advance!

Before I ask away, I just want it to be know that I've looked through several wiring charts, including ones on this site, and I still can't find the following wires:

- Door trigger/dome light:  I know the charts say either at the switch or behind instrument clusters, but these 2 spots are very inaccessible and too vague, respectively.  I have tried several wires near the light switch and behind the instrument panels unsuccessfully.  Does anyone know a good, accessible spot to tap in?  Can you provide detailed instructions on how to find it?

- Tach: The charts say yellow/red wire at EMU/passenger kick, but there are 2 wires with the same color there.  Does anyone know which it is?

Thanks!

one side of the switch is a ground connection the there other to the blue white activation input. and for your door trigger best bet is to pull of your panel and find the wires.

Hey Guys,

Thanks for the quick response!  I get the idea in theory, but I actually need to know how to physically set up the button.  Like where to attach the wires.  Here's what I'm working with:

Can someone tell me what the button is supposed to come in contact with when it's depressed?  How/where should I use the little red piece?  How/where do I attach wires to the actual button assembly?

Please excuse the newb questions, but I've never wired up my own button switch before.  Thanks!

RayDawg,

I wanted to PM you about a DEI 516L module but your mail box is full. Was going to ask if you could get me any info from the Directed web site that could possibly help me. The 516L works fine but will not make any announcements when going into the remote start mode. I've triple checked the wir connections and all is per the instructions. I'm using the 516L with the Matrix RS 3.5. Any help would be truely appreciated. It seems nobody on this forum knows the 516L enough to help me out. I've posted questions twice and plenty of reads but no responses.

Umm... I may not know much, but I'm pretty sure my alarm didn't come with a hood pin switch.  It DOES come with a push button remote start, and this is the only unidentified switch I have left.  I'm almost positive that's the remote start button assembly.  Anyone else have an idea?  Am I way off?

There are 3 switches that come with the Matrix 3.5. They are 1. The Valet Pushbutton Switch. 2. The Hood Pin Switch. 3. The Remote Start Bypass Toggle Switch. That's it as far as I know of.

Also, SoCalBluetooth, I have some info on 516L, but i have to unlost it.  I will try and get it out later today.[/QUOTE wrote:

All Right! Someone with some info! It's really wierd, sometimes the 516L will announce it is getting ready to start but then will not announce it is running in remote valet mode. I have yet to figure out why it works sometimes and other times it does not. The only thing I can think of is that there is a ground issue related to the starter kill circuit but I have the diode installed as called out for in the install instructions.

The other thing is sometimes when I have the alarm disabled the 516L will announce a intruder alert when I open a door. The remote indicates the alarm is unlocked but I go ahead and send a unlock command again and the 516L resets and no intruder announcements after that.

I know it must be something simple but I keep missing it.

Ahh... So I WAS way off! 

So... How/where do I hook this bad boy up?  And what is the instruction manual talking about when it refers to the H1/3 WHITE/ BLUE wire on the primary harness which is the "remote start (-) activation input"?  There is a diagram which shows a button hooked up to this wire, so I assumed it to be the unidentified switch (p.18 of the manual, btw).  Is that just some optional switch I have to buy seperately to hook up to this wire?  Thanks for your patience!  I'm at least starting to get the hang of it...

ok mrbean, first, hood pin goes hmm under hood.  just kidding.  find a spot along edge of fender well that will not get wet and cant be reached from outside that you can drill a hole through the flange around outside edge of hood and screw said switch into hole so that when hood comes closed, it pushes the switch into itself thereby disconnecting the ground from the wire that you will hook to the terminal on end of switch.  That wire will go to your alarm as an instant trigger, of the negative variety.  It does two things, first it triggers alarm if someone opens the hood the thieve you.  Second it disables the remote start when hood is open so that it cannot activate when you or some other dear to you is working under the hood.  Its a win-win for you.

Now onto the other, if I am not mistaken, (I dont have a manual in front of me)  this wht/blu wire you are refering to is for adding extra options to the remote start.  There are some modules on the market called page-start or something like that that are basically a pager that when you call the number from a phone, it triggers them to put out a signal to activate the remote start.  these modules would then hook to this wire and complete the circuit and your car would start.  I have never used one, and really dont see the sense, because if you are so far away that you cant start it with the transmitter and you have to call it, you most likely wont get to it before it shuts off anyway.  The only plausible idea me and my buddies ever had for one is it would be a bet you could always win.  So just tape the wire up and out of the waywith the rest of the harness, and go on about your merry way.  Enjoy.  And we are all starting to get the hang of it.

Oh yeah, SoCal, I have yet to uncover the info on 516L, but am still looking.  Will post as soon as i find it.

tbird: Ahhh... That's easy enuff!  I understand drilling!

Just to clarify, the hood sensor wire is the only wire attached to the switch, and when it goes to ground (when button is fully raised and the bottom portion comes in contact with the metallic threaded upper portion)  It prevents remote start and triggers the alarm if armed, right?

As for the wht/blue wire, if I just hooked up a regular 2 wire button switch, with one going to ground, and the other to the wire, it would just be a keyless push button starter, right?

Hi,

I've been spending some time doing research in preparation for intsalling a Clifford Matrix 3.5 responder system into my manual '89 240sx hatch.  I've read many posts on installing remote start in a manual tansmission, and I know the dangers involved.  However, I've found the wiring for the neutral switch in my car.  If I hook up the Matrix's neutral safety toggle to this switch, the remote start should pretty much function as safely as in an automatic, right?

A follow up to this is:  Is there any way to also hook up both the ebrake switch and the neutral switch to the neutral safety toggle so that remote start is only allowed when both the ebrake is up and the shifter is neutral?

Since I'm a newbie to wiring and electronics, detailed directions would be most helpful.  Thanks!

My advice is to buy a unit designed for a standard trans.

Save yourself alot of hassle.

Hey guys,

Almost finished with the install into my '89 240sx.  Trying to figure out the best place to put the antenna so it gets good reception but is still inconspicuous.  Right now it's under my dash, and the reception is crap.  The clifford site called it the "windshield-mount superheterodyne receiver,"  but there doesn't seem to be a good spot for it on my windshield, and I'd prefer not to have a wire trailing the antenna back to the brain out in the open.   Any ideas?

I put mine right behind the mirror on the windshield and tucked the wire into the headliner and ran it down the pillar to the brain box.

Yea I would mount it high up as possible.

i dont think thatll work becuase they work on different frequencies...

im going to be insatlling a avital 3300 on my 2000 neon.  i have been trying to place the antenna.  i dont want to stick it to the window.  but there is a small gap between the headliner and the roof, right next to the window, do you think this will work?  or will it be obsturcted?  also this will sound like a complete newbie question, but is there anyway to wire the antenna so it interfaces with the factory antenna??  that would be GREAT range

Hey all,

Just fiunished installing my Matrix 3.5 into my '89 240sx, everything works fine, but my tach is all whacked out.  The needle twitches wildly during deceleration when my foot is off the gas, and during hard acceleration.  I've done the tach learning procedure as described by the manual, and it's not as bad as it was, but it definitely doesn't behave like it used to.  The connection between the tach wire and the alarm is clean, no fraying or exposed threads. 

Anyone else have this problem with this particular alarm?  What could be causing this?  And most importantly, what should I do?

did you verify your tach wire with a meter?

and no, you cant combine your acc and ign wires together....
