Does anybody have experience...I have central aftermarket door-locks...meaning if you unlock one door the rest unlock.  Recently there was confusion in the wiring and I might have possibly shorted the relay that came with the kit.  As far as I can see I would have to order a whole knew kit when I already have the actuators.  Does anyone know of how to wire relays to achieve the same result as the one that came with the system?

All you should have to do is wire the motors like this

Then for the alarm inputs you would wire the pulses that the drivers door actuator sends out when you lock and unlock the door manually, you can also wire a negative trigger from the alarm to these wires. If the actuators dont have extra wires for the pulses then you will have to add a switch. It isn't that hard to do. Personally I would add a switch anyways.
