door lock switch diagram

possibbly the aftermarket kit you use will have 2 wires that require just a ground input from an alarm/starter systemto trigger the lock/unlock of the actuators.if the factory switch you are using has 3 leads to it normally the centre was 12volts that was sent to the actuator when pressed either for lock or unlock.try putting a ground to the wire that would normally have had 12 volts on it, then attach the wires from the aftermarket doorlock system (1) to one side not in use yet, then the other wire from the aftermarket system to the other side of the switch.this should only open a ground to either lock or unlock when the switch is used.almost all aftermarket doorlock kits have these 2 wires extra in the kit and after installing this kit it should be easy for you to figure the switch.John

what kind of car and what kind of switch are you using?My Personal Installer Note: Connectors are easy, neat, and professional. But do you know how to crimp properly?

I agree with what John says, you should be ok. Let us know how it goes.
