Hooked up the keyless entry today. I tested the various wires on the larger connector and I found that the White / Green wire is connected to the dash door lock / unlock switch. I spliced in my relays here. The doors lock & unlock fine, however, when I lock the doors via the remote, the factory alarm is not engaged. Similarly, when I lock a door with the key (factory alarm on) I cannot unlock them with the remote. I'd assume that I should use a wire that is connected to the door.
I tested the blue wire and found that when cut, the doors will lock with the key but not unlock. When my keyless entry relays are connected the remote will only unlock the doors and will not deactivate the factory alarm.

Man, this project has me scratching my head. I also tested the blue / brown wire. When cut, there is no affect on locking / unlocking with keys or dash switch. The only other wires Iíve not tried are the black and the orange / gray wires.

A summary:

3: Eight Wires
Brown -> ground
Brown / Yellow -> ground (?)
Blue -> driverís door unlock
Black -> (?)
Red / Gray -> power
Orange / gray ->(?)
White / Green -> dash switch
Blue / Brown -> no affect

Any suggestions?
