94 Lifted Silverado 6.0/4L80e swap Build

Going to try to test drive the truck tomorrow! I want to make sure I have 2 things right:

First I need to hook up my speedo/cruise control? In another post I read that all you do is access the vssb box behind the dash and find the lt. blue wire with white stripe and the red wire with white stripe and put both of those in the same end of a butt connector. Then on the other side of the butt connector put the speedo wire from the computer. Is this true? Want to make sure before I do it.

Second, my nelson harness came with 2 speed sensors but i only used one of them (hooked on the front of the tranny). Because I used my old obs vss for the second one. So what do I do with the other Nelsons vss? Just let it be? Thanks Guys.

Anyone for the above questions?? ^^^^^^^^^^^

I think you have to hook the second np vss connector into the t case and not use your obs vss connector at all.

I can not help you but in my case I plan to use this http://www.advanceadapters.com/products/pn-716073e/Advance Adapter kit in the 4l60e to np241 adapter.I will not wiring the 4 low signal to the PCM and flash 2WD tune...the trany should shift ok in 4 low but the speedo will think I go faster then I go in reality

Got the truck out again today. It wasn't shifting out of first, so I ended up cutting The rear VSS connector from nelsons harness and cutting my 2 wire vss connector on my t case and mated the purple with the purple in one butt connector in one end, and then the purple from my obs connector in the other end. Then I put the other 2 wires together as well so my obs wires are still getting a signal. That helped my shifting problems. As I came back from my half mile trip, i looked under the truck and found a empty plug that was by the front of the t case ( but not part of the t case) if was just a random 2 wire plug in the harness. I looked for the same connector and found a thick black shielded wire with two wires inside ( a purple, and I green i think). I hooked those up, took it back out and it seemed like it didnt want to shift. OF COURSE lol. there was also a black wire with a white stripe along with that sheilded wire, so i will have to mess with that tomorrow. trying not to make the neighbors mad going down my subdivision with open long tubes. Another problem- NO HEAT! the blower motor is working but i am getting no hot heat
