Finished up the wiring harness for this. The quick connects plug right into the engine harness. Most the other wires probably won't be used and will be trimmed once installed in the car. The only wires outside the plugs that will be needed is: +12v power, O2 sensor in, Fuel Pump trigger, and torque converter control.

I intend on adding a vehicle speed sensor and possibly a couple pressure sensors for fuel and oil and possibly electric fan control. Some of the other wires might come back into play for boost control down the road.
