1990 Honda CRX K20a2 swap and Kpro 37820 PRB A05 2068 502603 and my ecu is not turning on. No light inside, the fuel pump is not turning on, and it wont connect to laptop. I have the tune saved so that is not an issue, however I the wiring diagram I have found is not an exact match so I need to know exactly which wires provide power and ground off the ECU to properly test.

Before going any further you should test the ECU in a known working vehicle. If it does work, then you need to contact whoever made the harness that is in your vehicle and correct the issue or you could damage the ECU.
