Will have to figure out exactly which management system it is first, as you suggest. I thought the turbos were 4.3 and NAs 4.4, but the web is telling me different. Pink/blue, that's right (thought it was blue white).

By "pin out", I meant the actual positions of the connections on the ECU. If it's not the switching via the ECU, it's going to be the ground before the ECU for that circuit. Really a strange thing to happen, losing that feed. Unless a wire broke someplace--hope not.
