If you want to know the wire colors, I can list them. You can also try www.helminc.com

There is not really an "unlock" wire. The door locks are actually little motors with two wires each, not grounded. All the locks are tied together. These motor lock wires run from the lock motors, up to the passenger side switch, and then across to the driver's side switch.

The motor wires are pink/black and pink/orange.

What the door switches do is switch the polarity of the voltage going to the motors, so it reverses direction. One direction is lock. The other direction is unlock.

If you find the wires I listed above coming out of the driver's side switch, you could install a secret switch in series to break either wire, and that would kill the electric locks. But it's going to kill the lock and the unlock functions both.

It sounds like a could put a double pole switch that would give me ground and plus 12v. on the unlock mode.I could install a small fuse in each line, so it doesn't get crossed with the button pushed at the same time with reverse polarity...yes?
