So here is some of the wiring i encountered. Unfortunately, holley does not offer any true plug and play systems for a coil on plug setup besides the LSx engines. So i had to dig into the harness and add 9 pins. 8 were for ECU signal to each of the coils, and 1 ECU ground. I also had to tie into the holley ignition harness and wire the cam and crank sensors in.
