SR Wiring - Need some info

[Duwey]

I have a 90 fastback with an sr redtop. I am wondering about the extra green wires coming from the ecu. I don't have a check engine light but I would like to have it to troubleshoot. Heavy Throttle did the wiring and said there were no issues with it but I would rather have a diagnostics hooked up to see if the motor is running properly. Thanks.

Green, green/white, and green/black can all be connected to a CONSULT port. The other wire (yellow/green IIRC) on the port goes to ignition.
