I'm happy with the GM crate engine harness I used on my LS9-clone custom build. The only changes I made were adding pins to the ECU connectors to bring out the reverse lockout (RLO) output and inputs for a supercharger inlet MAP sensor.

I have used PSI for all my projects thus far and have had no issues
Like Jeff though, I am going to try out Speartech on the next build as recommended by my engine guy and tuner
