alarm wiring ??? AUTO WINDOWS

[kaceb]

Hello everyone,

I have been looking around on my 2002 au3 for a negative output cable from the factory installed alarm.

The reason for this is that I have a closure module that I took from my previous car which automatically closes the windows when the alarm is activated.


all of the other cables that I need are no problem, its just the pulse wire that makes the module work that I cant find.

I would appreciate any help with this, been messing around with it most of today ............

Ok fair enough, I guess no-one knows,

I have also been trying to find a wire from the central locking circuit, either positive or negative, when the doors are locked or unlocked. This could work wired through a relay to give me the negative switch wire that I so crave.

But am I correct in thinking that the central locking circuit works on a pulse, i.e. it doesnt hold the voltage , its only there for a second or 2 ?
Thats how it seems to test out.

So basically if anyone knows of a wire that changes state when the dorrs lock or the alarm is activated I would very much appriciate it if they would share their knowledge :

Yes I have wired auto window closers into the central locking. The only downside is they close whenever the door locks, regardless of what caused it to lock.

I cannot remember which one I connected it into, double check me with a multimeter. From memory there are two lines going to the actuator. They are both held positive. To lock one line drops negative briefly, and to unlock the other drops negative. My setup hasn't missed a beat and it is fantastic watching peoples jaw drop in car parks

Kaceb. Get in contact with Stav (useless here on the forums, yes we all know its a silly name). He has done a kit so to speak on how to get auto windows up.

Have a look at his thread. http://fordforums.com.au/showthread.php?t=70309

Thanks for repling

Yes I understand the briefness of it all, but I need a constant negative to work the module, i think,

In my last car it had a cheapy alarm and i just joined it to the negative that went to the flashing L.E.D.

If you're not looking for a negatvie trigger and you just need to ground it, there are heaps of places. The whole chassis is negatively grounded, depending on where you are locating your module there should be heaps of spots. Any unpainted metal should do it.

[kaceb]

I need a wire that becomes negative when the doors lock or the alarm is activated ,

LOL I understand that the car body is negative.

Ok then what I said before, use the line that runs to the actuator

[TwistedEL]

It's easy enough to test if it needs constant or just a trigger
Just touch the trigger wire on the module to something metal

good thinking , ill try it 1st thing in the morning and let you know how I get on

thanks for taking the time to help

what about latching the modual with the alarm trigger output ?

[kaceb]

yes yes yes

thats exactly what I am looking for

do you know where it is?????????????


please say you do

I have been looking for 2 days with my head in the foot wells

ok guys in defonatley needs a constant trigger,

I earthed the module control wire to the car body and the windows went up perfectly, as soon as I lifted the wire from the car body the windows stopped dead.

All the door panels are back on now and car put back together, apart from one little wire poking out !¬ LOL

if you need a constant negative trigger? what about using electronics to get ur desired constant negative signal?

if from what i am reading that a negative pulse is sent, feed this pulse into an integrated circuit (I.C) Ask jaycar, or dicksmith electronics to help you out on what you need. i am thinking of a AND/OR gate to get your desired result. from memory the charestestics of these and/or produce a postive or negative signal depending on the inputs.

A capacitor, couple of resistors and a transistor should do the trick.
A relay too depending on how much current is required.
