ECM for auto to manual conversion

[nick94]

I almost have all the parts needed for my conversion. I found a parts truck that has a manual transmission with a 350. The donor truck is a 1995, my truck is a 1994 both with 350.
My question is the following can I use the ECM from donor truck on my 1994? I am hopping to avoid all the expected codes after removing the auto tranny from my truck.

Not 100% as the 94-95 auto and manual had a few differences in teh control systems. I know that 94-95 autos used a 3 wire heated oxygen sensor whereas teh 94-95 manual used a 1 wire non heated. Teh heated O2 is prefferred, but not sure if any wiring changes took place or not along with it. All you need to do is find a PROM chip that will work for what you are after. Chances are if teh 2 ECM's are teh same part number, it will interchange, but GM did use a few different ECM's in the later TBI years.
