    Havent dug through diagrams yet. Oops, ill find it in the morning

    anyways

    reworked my harness. Came out AMAZING!!! :)

    2 questions though.
    i have 2 wires for the 'vss buffer' left and it is dark blue and brown....
    my vss wires are light green with black tracer and purple with white tracer....
    they both go to the tranny 'c connector' and come out as blue and brown.... Can i splice them directly into each other?

    2nd question deals with the o2 sensor.
    i have 3 wires.... 1 is purple which goes to pcm, another is ground, and the last is pink with white going to 4wd fuse?
    do i need this shit or can i ditch it? Lol

    other than those 2 questions, everything looks and turned out great!
    :)

    I had actually talked to a friend, he said on the trucks the v.s.s. buffer recalibrates the signal when you put the truck in 4low. Just what i was told. The 3 wires for the O2 are for running a heated O2. Pink/white should be power, purple should send the info to the pcm and black is ground.hope most of that is correct.
