Okay I have some questions and have been doing a lot of research. I am putting the 5.3 vortec in my 93 camaro already did the k member and all that. Only thing I’m stuck on is which harness option to go with. I have address to a full body harness from a 01 ls1 car no engine harness though. So my question is will the 5.3 harness connect to the body harness of the camaro?

You could go with a Standalone Harness like our HAR-1018 which will run the engine independent of the body harness. Its a four wire hookup so you don't have to worry about tying anything else in.

I used psi harness and an ecu from them. 1st class product and customer support.

I have a PSI engine harness in my 70 El Camino with a 1999 truck 5.3 L motor. No problems. Good documentation. Look at their option list and buy whatever you might need now or in the future for air conditioning support, etc.

These options are low cost but best done now rather than later.
