94 astro v8 swap

[meglaman]

I'm putting a 91 350 tbi into my 94 vortec astro van. I need help with the engine wiring. What computer do I use and which wiring harness?
ANY help would be great. Thanks

Have you considered buying the JTR manual on this swap? They're very thorough and will answer your questions. I put a TBI 350 in my previously TBI 4.3 and it went pretty smoothly, all things considered. I reused the existing harness (because I stayed with TBI).

(EDIT: I did extend my entire wiring harness, but this was tackled one wire at a time, soldered and heatshrunk, in order to be extra cautious about a heating issue. It turned out to not be necessary- and it was also mentioned in that very same book!)
