I have an '84 z-28, bought it without the engine and tranny. Was used as a drag car, the ecm was pulled. I have a 305 tbi out of a 91 Chevy caprice. Before giving it much thought I bought a wiring harness for an '85 z28. Should I get one for the caprice or will the camaro harness work and before I buy an ecm wanted to be sure I got the right one. Ecm for the 85 camaro or 91 caprice???
Any input will be helpful and appreciated. Thanks

 

An '85 Camaro harness will be either TPI w/MAF, or carb. If you want to go TBI I'd get an '88 through '92 TBI (VIN E) EFI harness from an f-body. And the ECM to go with it. Note that in '90 VATs was used in the f-body's.
