Wire harness swap
Hello guys I have a 93 corvette and want to build it a bit. I am pulling the engine out for a full reseal/ rebuild. I want to swap over to a 94+ harness. Is it worth it? how much of it is actually different or do I just go stand alone and fab up a harness. I want to track this car.

I believe that would be a challenge since the '94 is SFI and a '93 is still Speed Density. An M6 would certainly be easier than an A4 because the PCM would be expecting a 4L60e. I believe that with the known '93 ECM issues maybe it's time to consider an after-market control/set up.
