Well the wire pulled through the firewall and broken not by the pcm. it is a single wire with its own wire loom. My buddy has an 01 GtP and his does not have this wire.

Update wire is connected to pin 21 on ecu connector. I beleive this is the performance shift wire. where does this wire go inside the car?
