04 Corvette PCM I'm having trouble finding the correct pinout for SERV NO 12586243 HDW NO 12583659 for a 2004 Corvette. Ive found similar pinouts on which wires to remove and keep and such, but nothing that's 100% This is what I'm going off of http://www.dpars.org/Corvette_PCM_Pi...tor_Pinout.htm and everything from that pinout matches. I tried LT1swap and didn't have much luck there either. Basically I'm trying to configure this harness as a stand alone with no a/c or emissions, but with cruise, and a 4l80e while saving money instead of buying a new harness since this ones in perfect condition. thanks a lot yall. Oh and if youre curious its going into a 1970 Camaro

If you're looking for a "remove this wire" type deal, you're probably not going to find it. But using this guide for a truck from LT1Swap, and the one you posted will work, as they are almost identical. You'll just have to compare them for yourself. I looked at them quickly and would use it myself, especially since you are wanting to add a 4l80e. http://lt1swap.com/2004vortec_pcm.htm

Yeah I was looking for a wire removal guide. I just don't want to mess this up. Like I removed the rear o2 sensors, and the wires for the a/c already since I know for sure I don't need those for the engine to run. I had looked at that one and it was the closest. I guess my biggest question using that guide is, do the circuit numbers and wire colors have to match 100% or is it just the pin location that matters?
Circuit numbers are useless to 90% of the people doing a wiring harness. Color doesn't matter either as long as you know you are looking at the right wire, insulation color doesn't affect current flow. But yeah, basically it's pin out location that matters along with making sure power and grounds are where they're supposed to be. If you see a pin out that appears to be different on the truck diagram from what your Corvette one shows, then I would find that schematic and find out why it's different. If you have a basic understanding of wiring, then it really isn't too hard of a job, but it is time consuming. Just take your time and be thorough and you'll be fine. If you remove something that you shouldn't, just go back and put it back in. Patients is key, and double and triple checking your work will pay off in the end. If you need a schematic for a certain circuit, just ask and I should be able to post some.
