Red Headed Stepchild-75 Swinger LSX Swap

The issue with going with an OE harness and PCM is that you still either have to spend $600 on HP Tuners to tune it, or hire someone to tune it for you. So by the time you're done, you're still probably $1k into it.
What route are you going Dave? The wiring is the one thing stopping me from starting on the swap right now.
