The CAS connectors on the Haltech CAS sub-harness are the same color. They're not white and grey like the stock harness. The Haltech instructions label their connectors as "home" and "trigger"? Which one corresponds to the white and grey connectors?

 

The HOME connector goes on the sensor that picks up the Single tooth signal and that sensor is the closest to the driver side. The TRIGGER reads the inner 12 teeth and the sensor should be closer to the crank, timing needle, and the passenger side. This is if you're on the OEM crank disk of course.

 

Thanks for the explanation! Yes, I plan to use the stock CAS for now.
