Who is building your header? Help me out with the wiring and getting a hold of a harness, and i'll help build you a header off my car once i have the swap in place... <shrug> At least then it'll fit for sure... heh.
Small sampling of some other crap i've built in the past:
My Gallery 
I'm planing on running the TSX TB, so i'll be using the drive by wire, so i shouldn't have that code come up with my setup, and if thats the only code, and all gauges work, then thats fine by me... haha!
I have everything ready to go for my swap, just need to sort the wiring... i won't start the swap until i have a solid direction with the wiring already in place... i can't have my car be down for that long, ya know?
