I'm having problems finding the lock and unlock wires in this car. I found one wire behind the glove box that shows 12volts during unlock, but when I pulse it with the alarm it does nothing. I found one wire in the pass kick panel for lock and it shows 12volts when locked, but I can not make the alarm pluse it either.

What kind of circuit is does this car use? Reverse Pol. or something else.

I hope someone that has installed an alarm on this car before can reply.

Thanks DJ Rob

Your lock and unlock wires are in the factory alarm plug behind the glove box. Its a black 12 pin connector

Lock=Lt.GREEN / WHITE

Unlock= blue/red   both pos(+) pulse
