Ok, so ive searched and searched and cant find any clear answers. I have a 2.5l with auto tranny in a 91 s10 and im wanting to put in a 350 Tbi. I have a complete motor with ecm and auto transmission. The only thing I dont have is the wiring harness. I basically just want to know what am I going to have to do about the engine harness? Do I have to make one or can I just get one from a 4.3 TBI with auto transmission? And if so will my factory gauges work with that motor since I have the V8s ecm?

I done this ONE time!..its easier to replace the dash and the engine harness from a 4.3 and hook it up and go!
