what is that brown wire you have going to the power lug on the alternator for?

For my gauge cluster. I think I can take it off because the gauge works whether or not that wire is hooked up lol

Got more done tonight. Went and bought the oil cooler block off plate, gasket, and bolts (yes they are shorter than the bolts with the oil cooler). Cut out the lines and tossed em, blocked off my ports on my radiator, and installed the plate. Fired her up and let her run for a little bit. Love the sound of it. I have open headers on it right now but its sooo much better than the old crappy tbi motors thats sound like open manifolds. Also wired my autometer tach up. Can anyone tell me what wires I hook up for my stock tach, and my speedo? OH ya and I ordered the brake booster vaccuum nipple, should be here wednesday it was only 4 bucks. Once thats here it will be ready for a ride down the road!!!

Are you talking about the EVAP right behind the throttle body? Yes I did block it off. Its just for emissions.

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.

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
