Having problems with the central locking, buttons were not working so trying to retro fit a Steel Mate 386M system (bought from Jaycar). Trying to find out what wiring is in the drivers door that locks and unlocks all the doors. We have power we have earth, we have the wire from the original wiring that locks but when we hook it up to new wires it wont stay locked. None of these wires will unlock or lock the drivers door. Does anyone know what wires from the original Nissan factory unit operate the master actuator in the drivers door. We have tried all the wires in the original wiring harness and none seem to work the drivers door.
