Wire C which is red goes to the shift solenoids on the 80e. It's been a while since looking at that manual. LOL

This is likely your schematic. I believe the other was for 92 and earlier. E "would" be the correct wire for your power to the noids.

Hey Red I am working on this right now and I couldnt find any wires from my brake switch that have 12 volts at rest, then 0 volts when u press the brake. I have a yellow wire that is the opposite that has 0 volts at rest, and 12 volts when you press it down. Then I have 2 purple wires that have .95v at rest, and 0v once you press the pedal down. So I am not sure which wire I am supposed to use. Thanks again for all your help

I'm thinking it's the purple wire. Pink has 12v all the time and purple switches off when the brake is pressed. The other wire you're seeing may be brown instead of purple.

Yup the pink with the stripe had 12v so I'll try hookin up the purple. Thx again
Truck is running/ shifting good, and when I come to a stop now it doesn't want to leap forward and stall out.
Still have a few issues.
No Speedo- Going to try reverseing the 2 wires on my rear vss on the t case.
Tach is still way off
When trying to confirm RPMS through a scan tool, the OBDII port cant make a communication with the ECM????? Is that because Nelson Locks it?
And last is a 4x4 issue. Back with my old setup with the 350 and 4l60, i could put it in 4x4 on the go with out a problem, it would hop right in gear whether it was 4L or 4H. Now when I try to do that, all it does is grind really bad so I have to shut the truck completly off and engage it. Even if the truck is in park or N it still grinds

Been driving around with GPS latley because your speedo doesn't work? Me too. Enough of that. Take your LS harness and find the rear vss connector with the Blue and Purple wires. Find your OBS rear vss connector with the Blue and Green wires. Connect the LS Blue to the OBS Blue. Connect the LS Purple to the OBS Green. Now access your vss buffer box located behind the glove box. It is the little white box. Find the solid blue wire. Cut it before it goes into the vss buffer box but leave enough room to connect a butt connector. Take you LS speedo wire and the blue buffer box wire and put them in one end of the butt connector, then put the other blue wire coming from the speedo in the other end. Should have a working tach then. It does cause your brake light to come on and I dont know why, but atleast you now have a working speedo. NOTE: If you unplug the buffer box it will cause your brake light to come on as well

Have well over 500 miles on the swap! Runs awesome and I love it. Cant wait to head and cam it. A few small things I noticed....I have 3 vss connectors on Nelsons harness????? I am not sure what I am missing. I have the front one plugged in to the front of the tranny (4x4) and I have the rear vss plugged into the rear of the transfer case. Theres an extra vss connector thats inbetween those two. What am I missing
