I removed the engine wiring harness from my efi car. I am going to carb.

If I get an engine wiring harness from a carbed camaro, will it plug into the fuse block where the efi harness did?

 

Probably.

But, you didn't really need to remove all of the EFI harness. Everything you need to run the carb system is there in it. Whether factory carb or EFI, the same effort is required to go to non-computer carb.

Although the '82-'86 V8 distributor harness will plug right into a non computer controlled HEI distributor. Big deal, it still has a bunch of stuff you don't need.

To boot, the location of the alternator and AC switched between '87 & '88. If your car is '88-later, an '87-earlier carb'd harness is going to require more modifications to run a non-CC carb setup than the '88-later harness would.

 

Well, I sold the efi harness.

I am going to be running an msd ignition set up, as well as a small 'race' alternator. Ac gone.etc..

The car is becoming a drag car, big block swap.

 

Custom wire it. You may want to get another harness to get the plug, but for the sake of cleanliness, run and wrap your own wires.
