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.

Some updates...Been driving the truck up and down the road alot. Shifts better and better each time, I think it wasn't shifting good before because I did a fluid flush and it prob takes some time for all the fluid to work itself back into the valleys and grooves. I bought a autometer triple pillar pod for a temp gauge, oil pressure gauge, and air to fuel ratio. I will let you all know that it fit like a peice of CRAP. If you are going to buy one, and your are like me who is really picky and like a nice clean look to things, DO NOT BUY IT. I had to hack mine all up just to get it to fit. I will probably end up writing autometer because its a shame. One the good side, I did end up making it fit so its in its 95% stock location. The 2 main problems is it was hitting the windsheild, so you couldnt get it to clip into your a-pillar, and the bottom edge was too long by about a half inch (the edge thats near the speaker on the dash). Good thing i am a collision tech or I would have gave up on this stupid 60 dollar part. Ended up trimming it and grinding the edges down so I was able to clip it back in. Another bad thing: The black color. They dont make them in interior colors so i will probably end up getting some blue interior paint from LMC and spray it quick.

I will have to get u a pic for the rear vss. I don't have my pns switch wired up bc my truck is a 94. Is ur 4wd working? I can explain how I did my rear vss on the tcase but I think pics will b better. I cut nelsons rear vss connector and cut my obs connector . I took nelsons purple wires and put it with my blue wires I think from the obs. Then I took nelsons green wire and put it with the obs green I think. Then I put the stock obs connector on. So u will have two wires goin through a butt connector to one wire and then two. Wires goin through a butt connector to one then the obs connector

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

Sumthins up...my t case is extremley loud when I am slowing down. It makes a terrible grinding noise. It isnt constand though. I sounds like someone grinding gears trying to get it into gear. Theres like "pulses" of grinding like RRRRRRRRRRR...(1second)......RRRRRRRRRRRRRRRRR.... (1second).......RRRRRRRRRRRRRRRRRRr and so on. It only does it when I am coming to a stop. It does it from about 20mph to 0. Then it will do it for a little bit more while I am at a dead stop. Sounds like a buncha gremlins crawled into my tcase! What could it be? Dam 6.0s just have too much power lol
