July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Ground Circuit Continuity

Check resistance between GND (ground) terminal of cruise control ECU wiring harness connector and ground. See Figure. Resistance should be zero ohms. If continuity is correct, go to ECU-IG FUSE. If continuity is not correct, repair or replace wiring harness or connector(s).
