What makes me think it's not factory is that all the wires are the same color. GM color codes their harness except for replacement pigtails, which all I've seen are white wires on the replacement pigtails.

They arent all the same color, even though it looks like it in the pic. THeres 2 yellow and i believe a black and white. It's tied into the factory harness and looks 100% factory with no tape, connectors or anything.

What I need to know is where it gets its signal from for power.

I replied in your thread about nelsons harness. If your 94 is like my 92 there's a lil power block under the dash on the. Drivers side that the 4x4 system gets its power from. So all of your factory connections for the transfer case stay execpt for the vss one. And like red said the reverse lights are in the with the colum because our trucks didn't have the switch on the trans like the newer ones do.

Thanks, Since our trucks didnt originally have that switch on the tranny and my new tranny is a 2000 that had that switch and i removed it....thats ok right?

Yeah. I don't have the switch on mine. I've never had a problem with mine.

Received Nelsons harness today. I am stunned with how clean it is! You could easily make your engine look like it has no wires running to it. All of the wires are the right length and I had no problem reaching any thing. I AM VERY PLEASED WITH IT and would recommend it 100%

The only question I have is I cant figure out what to do with the VSS connector. The 2 connectors on my trans case are for my old OBS harness connectors, and the 2 connectors on my tranny are already connected ( 1 is the giant 13 wire connector, and the other is the 2 wire connector about 6" away)

I think the 80e has an input speed sensor and an output speed sensor. The output speed sensor should be around the output of t case

Ya theres 2 sensors on my tranny (which I have both plugged in) and 2 sensors on my transfer case (which I plug my old OBS connectors in). So I have 1 left over VSS connector from my nelson harness. I have got to be missing something lol.

I think you have to plug the np harness into the output speed sensor on t case and also plug np harness into the input speed sensor on tranny. I dont know about the obs connectors. Someone will chime in and help
