I have installed a remote start in a 2003 Malibu. In order to make this work, I had to purchase a 791 bypass module to get around the Passlock. As near as I can tell, this module starts and runs as long as the remote start allows the 791 to find a ground.
I wonder if a 791 could be wired into my 2002 impala with a manual switch that would ground the 791. Then, if I once again saw the security light, I could flip the switch, ground the 791 and start the car. Once the car was running, I could unground the 791 by flipping the switch.
I do not think that a remote start would be required and the wiring would be pretty simple.
Has anybody tried this?
