Manual to Auto wiring harness

I am changing my car from manual to auto. I have found a Z28 here locally that is the same year as my car (1995) and plan to pick its wiring harness. What I am wondering is can I just cut off the auto trans part and solder it into my harness or do I need to get the whole harness from the engine, ecm, and trace the wires into the fender and remove them from the body? Thanks

Cutting stuff off kind of defeats the purpose, because you want those wires to run to the PCM. Swap the whole harness IMHO.

Listen to Rob. He knows what hes talking about. Or you can put in a 700r4, TH350, Th400 and not worry about any of that.

I would love to do a 700-R4 swap but I already have 2 real nice 2000 year model 4.3L S-10 trans. I have been told by PCMForless that he can make my 1995 ECM shift and provide a good signal to the speedometer for that trans also.

If you can get the engine harness that is the simplest. I added in the trans plug to my harness when I swapped to auto. You will also need to add in the wiring on the auto shifter for reverse lights, p/n signal to pcm and move the wires from the clutch start switch for p/n starting.
