Just wondering if any one has done a remote start or alarm on one of these. The tech soft says Multiplex - lock is neg trigger with 470 ohm resitor and unlock is neg trigger. I have the 457GW which I thought would do bothe passkeyIII bypass and the door locks but theres a note on tech soft saying the 457GW wont work on this model year for the door locks. It does say you can use the 456LW for the door locks. Any one see any differance other than simplicty from using the 456LW vs relays and resistors? Or know why the 457GW wont work for this car? Just wanted opinions. Thanks
