very direct question about TPI

Hey guys.. I am doing the TPI swap on my 92 5speed TBI car.. I will be using the TPI on a new 355.. I already know it will need alot of computer work but my question is what harness to get.. I am wiring STUPID.. one with labeled connectors would be best.. maybe even a harness that just changes from TBI to TPI?? I thought I heard something about "repinning".. I just want the easiest way out on this because I absolutely HATE wiring stuff up.. I have no smog equipment so that doesnt matter.. since its going to be a pretty stout engine i dont know if i should go SD or MAF.. I would just buy a complete setup on ebay but im almost convinced i would get it and the harness would boggle my mind.. any suggestions on something easier?? cost not too much of a factory on this either

I dont know if this will help, but im doing my wiring harness from painless wiring. It came with an instruction booklet and all the wiring is labeled. The cost you might not like though, $300.00, I think its more if you go with speed density.
