VATS, need to have the pcm tunned with VATS disabled. Or have a good remote start guy come over and take care of it for you.

i still have the whole dash to the truck. i ripped out the key system from the sterring colum. there were 2 wires going to a swith type thing. just push a ****.. then there was 3 wires going to a plug in on the key assembly. look like they had resistors in them. is this the vats??? i tried lookin for the orange wire.. didnt find it.. i cant find it!!!

you can't just rewire it, it needs the body control module also, just get the PCM fixed to disable VATS. If everything is there you could try to do a relearn on the theft system
