1989 305 TBI to 350 TPI
i have a 89 rs tbi and im gonna be swapping a 350 tpi. i have a speed density harness but i was told im gonna have problems with the bulk head connector and the vss. i dont really wanna re pin my tbi harness either. Would it be easier to swap a MAF harness instead of MAP harness? im getting alot of mixed answers so if you guys could help.

You'll be doing some minor repining on any harness that isn't a 1989. Even then you may have a couple of pins but to be honest it's far from difficult. I'd prefer the speed density for the newer ECU but a 1989 MAF harness will be the easiest to swap in.
Check the wiring diagrams and decide which you prefer..
