I've got a 2001 Suburban LT 4x4 with the 5.3L. I've installed my Avic N3 but cannot locate the VSS wire. According to DirectWire it should be GREEN / WHITE at the ECM, pin 50 on a red connector. My problem is that my ECM does not have a RED connector on it, they are all black and there are TONS of GREEN / WHITE wires. If anyone out there has some more specific info or first hand experience I would really appreciate it.

Thanks, Shawn

There is a GREEN/ wire in the radio harness plug between a green wire and a light blue one. This is the VSS wire. The red part of the ECM connector can only be seen when removed or some are actually lableled on the ECM case itself.
