My car was supplied with Autoloc remotes, remote module and one motor control unit. I know I'll need a second motor control unit. I recently sent my Infinity master cell Back for reprogramming. Jay at Infinity was VERY helpful and involved with implementing the changes I requested. One request was to open circuits to power the door motors. I'm at a loss how the Infinity systems positive circuit interfaces with the negative signal the Autoloc remote control and motor controls require. Does anyone have experience wiring these components. A simple wiring diagram would be helpful.
