Hello!

I have a 1999 GMC Yukon SLE 4WD SLE, 5.7 V8 4x4 with the 4L60-E Transmission +Tow and I have a doozy of a problem. VIN: 1GKEK13R7XJ736183

I was driving in very heavy rain, went through a puddle and somehow the water moved the transmission wiring harness against the drive train. This ripped the wiring for the oxygen sensors, VSS, Park & Neutral position switch, Transfer Case and probably other stuff I missed. Basically the full Transmission harness. ::SIGH:: I was able to limp it home after using some Irish American Engineering to get the transmission hooked up, but no VSS, etc.

I could have someone splice everything, but I would much rather replace the wiring harness, and for the life of me, I cannot find the part number(s) that represent the underbody wiring harness that covers the items I wrote about above.

Before I became disabled, this would be something I would tackle, but these day's I would really prefer that it be worked on by a mechanic. When I call around to the parts yards I get the classic "Huh?" then they ask me if I have the part number(s) so they can cross-reference it, followed by silence because I can't find it!

I hope someone can help!

I have a bad connector to the speed sensor.it is a 2 wire connector but it has a solid ground wire with the 2 wires with a foil sheath around it. I believe to be a ground. When I cut the ballot frayed wiring I didn't notice it. Wired 2 new wires into plug. Never saw how friend wire would be connected. Only replacement is a gm generic connector. Need some advice what the purpose is and it's it really necessary. Other connectors do not have it.
