One way is to remove the left rear trim panel where the sub woofer would go and look for a connector, tied up to the harness that runs in that area.
I just looked up the wiring in the GM wiring diagrams, and hate to say they are incorrect, so I cannot say what type of connector, or what color wiring would be there.
(Guess I'll notifiy the right people on Monday about this problem in the wiring.) </div></BLOCKQUOTE>

Since you have access to wiring diagrams, I can't find an service literarture available yet.
I'm doing an aftermarket Nav system and i need to locate the VSS lead to the ECM can you locate the color/pin out? I assume the ecm is behind the glovebox like most GM Products </div></BLOCKQUOTE>
System is down, I'll have to try tomorrow. Saturdays nights and Sundays they do maintenance on the system.
The Hummer I believe has PCM (powertrain control module) which contains the ECM and the TCM (if automatic trans). In addition, most GM vehicles have the PCM or ECM located in the engine compartment; the BCM is the one located under the I/P.
So, which signal wire do you need. The actual two wire Vehicle speed sensor wires, that normally go to the PCM (or ECM), or the speed signal the PCM (or ECM) sends to the BCM to calculate mileage, and then sends the signal to the I/P speedometer/odometer?
I'll try later to see if the system is back up. But it might not be until tomorrow.
