Any one know how to turn the radio off after the remote start turns off besides telling the customer to leave it off before they get out of the car. Same applys to a 03' ford diesel. THANX

The easiest way I would guess would be not to power up the accessory wire. You do not need this wire to make the system work. The ac and heat at are on ignition circuits.

On all of the 03 gm suv's the brown wire does not control the radio it is you can leave the brown and the orange disconected and the radio will still power up. It is a class 2 databus system with no switched. Not hooking up a accesory will not work.

You need to pulse the drivers door latch wire on shutdown , to simulate the customer leaving the car.

hope this helps
