I have been talking to Speartech to reconfigure my harness ($450). There are many vendors out there who will do the work. They will rework the harness and computer(PCM) so that you are only left with a 4/5 wire hookup with instructions. LT1Swap provides info to do it yourself (you will still need you PCM reflashed), but I am electrically illiterate so its worth some cash to have it done for me. YMMV. I hate admitting my shortcomings but working 60+ hrs a week, its not something that I want to learn. lol!
