    For the speedometer I ended up splicing the vss wires from 04 computer into the vss wires on the transmission this makes a 3 wire splice for both colors (6 wires total) that made my speedo start working

    Take the vss wires from donor harness and just splice them into your existing vss wires. Your existing wires will stay hooked up as original.

    x2 on that!! I did the exact thing as this and it works just like it was factory. I also used the white wire on the coil for tach signal and the red for switched power to my coil packs and injectors. but i didnt have to use a resistoron my tach and mine registers right so...

    Thanks much!
    I started tearing through my harness today, and it appears my IAT plug was cut off. Didn't make me happy to discover that, but IAT harnesses are easy to come by so I suppose it could be much worse.

    Gotcha. I've got my engine side stuff basically set up. Not going to sweat the rest of it until I have an engine to mock it up on.
