I thought it was a jumper at the headlight switch or FCM...
Its tough getting old...[/QUOTe.
I used my bullydog programmer, but there is a thread that shows how to do the jumper wire, I also used my programmer to turn on daylight running lights on my 07 mega and to turn off seatbelt buzzer and turn up cold idle, adjust speed limiters and speedometer for taller tires, good luck, Monte
