Hey guys,

I'm having trouble trying to find out which end of the lock & unlock wires is to the motor and which is to the switch. (5 wire alternating locks) I've opened up the driver's kick panel in my '90 taurus and located the harness with the lock/unlock wires. So when I cut them how will I know if the end coming from the door is for the switch and the end going away from the door is the motor & vice versa...??? Or will I have locate other wires in the harness that lead to the motor? And how will I know when I test them?

thanks

once you have cut the doorlock wires, put your black MMeter probe to ground and the red to one of the wire ends. (if using a test light, clip it to ground and touch the tip to the wire ends.) work the switch on the door to UNLOCK, you should see the MMeter show 12volts (or testlight will light up) when one end of the pink/green wire is touched and the switch is moved to unlock., then touch one side of the pink / YELLOW wire (same side as the pink/green you just found) and then move the door switch to LOCK and there should be voltage on the wire. You have now found the switch sides to the wires, be sure the door switch is always moved to LOCK or UNLOCK when testing the appropriate wire. Now to absolutely sure, use a gatorclip test lead or a spare peice of wire and a fuse (5 amp), clip one end to 12v+ and the other end to one fuse blade, then touch the other fuse blade to the suspected motor wires (opposite sides ofthe switch sides), this should LOCK or UNLOCK the doors depending on which wire you touch. If the fuse blows, you've got the wrong side.

If you need the relay pin layout for the 2 relays, just let us know.

Most manufacturer's have the BCM or RKE module in the cabin of the car. What happens is the switch wires go to the BCM/RKE and from there it switches colors ( which is also referred to LOCK MOTOR wires ) and goes to the motors. If you find the wires in the boot, chances are this is the wire between the switch and the motor. The only time this is not the case is when the manufacturer decides to put the module in the door ( Honda Civic 1998 + ) but then Honda doesn't use a 5 wire system ( Thank God )

no problem, glad to help.

BTW, the 2000+ Civics have all wires in the kick panel and all modules are now, multiplex's. The fusebox is the main multiplex and almost all runs through it.
