I am installing a Compustar CS800s with a Fortin INT-SL+ in my '06 Rendezvous.
The Compustar has a green igniton wire that I currently have hooked up to the green ignition wire on the car. The compustar also has a blue wire that you can decide it's function with a jumper. Default is Ignition 2. I have not connected this anywhere. Do I need this on my car? If so, where does it connect and do I need to move the jumper?
The Fortin unit has a pink ignition wire which I thought would go to the pink ignition wire in the ignition harness of my car, but I see 3 pink wires in the harness. Which one is it? Is there a way for me to test the wires to see which it is?
