When i say ground signal i mean a GROUND. The Relay needs ground on the white/red to make the relay switch. The ECU always used ground when possible instead of Positive voltage. So with that being said the ECU connected the white/red wire to ground internally so the relay gets the ground it needs to switchover.

Jumper it and bring it to the meet

Edit: What year is your car? 97 right?

Edit: When you say you traced it back, you exposed the wire from the harness correct? every inch of it? If you didnt, the wire could be shorted to another wire and that would cause the 12v on that wire. The ECU wouldnt expect any difference because it sees 12v from the relay.
