Help with harness converions please.

Hey i have a 93 camaro with a blown 383 lt1. I want to convert the engine harness over to a 94 or 95 so i can run a maf. So it will be easier and cheaper to tune. So heres my questions, What year harness is the best to convert it to, or is there any difference in 94 and 95 harness? Also, is it even possible to convert just the engine harness over to a later year or do i have to rerun the later harness thoughout the interior of the car to the guages and stuff? I know ill have to convert the pcm over also. Thats the most important question im wondering, about the wires running from the pcm through the inside the car. Last question. I know for mustangs they make just a add on system for adding a maf sensor, do the make anything for a 93 camaro just wondering thanks?

Goto Shoebox's site shbox.com and compare the wire locations on plugs C100, C105, C210, C220 and C230. Get yourself the harness from the 94-95 and then repin those connectors so that you don't have to replace the interior harness.
