1997 Ford Explorer factry alarm interface

umm I tried that and the interior lights came on when I armed it, anyone else have an idea , or would the relay thing work?

The drivers door pin wire is yellow/black in the drivers kick panel. If that wire sees ground when the lock wire is triggered then the factory alarm will arm. On a Compustar alarm you just connect the rearm wire to the door trigger, and the lock wire to the lock wire and everything works. On a DEI unit I don't think that method works because of a timing issue.

Take the - doorlock output wire of the aftermarket alarm and connect that to 85 of a relay(but also remember to leave it connected to the doorlock circuit as well). Diode isolate. Connect 86 and 30 to 12v+ with a fuse (10a should suffice). Connect 87 to the vehicles door trigger + wire from the pinswitch. (This is the same wire you will be connecting the alarms door trigger circuit to, usually violet from the alarm harness). diagram on the way. Should do the trick.  Good luck and keep us posted.

"Connect 87 to the vehicles door trigger + wire from the pinswitch" what colours that? I know it has 3 wires from the back of the lock cyl and 2 that come off the latch

ok it wont work (either method, yellow with black stripe wire goes up in the door loom not down, oops), the stock alarm to be armed without a remote (unless you can figure the module out) the dome light has to be on and the door has to be locked within .5 to 1 seconds minimum AFTER the dome light is turned on, not at the same time. The way the aftermarket alarm works is it sends a signal from all outputs at once with no delay on arm, so if theres a way with a COmpustar or some electronic device that sends an output after roughly 1 second (all I do is set door locks to 2.5 seconds and add this device), any ideas where to get soemthing,modify a light flasher or something?????

I did a 97 explorer that drove me nuts! I tried the timing relays and all that crap but what worked the best--and I've used it on 2003 explorers too--is to get into the keyless entry pad. If your vehicle has the numbered key pad on the drivers door you can press 7/8 and 9/0 at the same time and the doors lock and the factory alarm arms. What happens when you press those buttons is that the wires that go to them are momentarily grounded. In the driver's kick panel you will find those wires, one is solid yellow, the other is solid red. I don't rememeber on the 97, but on the 03's I pried out the keypad and used a DVM to make sure I had located the correct wires--they're pretty small and they'll be close together. Take your lock wire from the aftermarket alarm (assuming it has a momentary negative pulse)and split it into 2 leads. Hook those leads up to the yellow and red wires. Be sure to use a diode in each lead, stripe pointing to the aftermarket alarm lock wire, so that you don't permenantly connect the 7/8 and 9/0 buttons together. Fast, easy, and works reliably.

haha thats brilliant, never thought of that, I was going to wrap up the dash and kick panel if I never got any responses, I'll give it a go!
