Hi. The auto-elec that I was going to see is not able to look into this for me right now, so I've engaged another that actually installs aftermarket cruise control and knows his way around existing systems.
The plugs for where the clutch pedal was installed have been taped over with duct tape. I could not find the clutch pedal switch installed, however, there is a wire wrapped in conduit hanging down over that area. It has been snipped and just left hanging there. Black, green wire and another white and green wire, both wrapped in corrugated black conduit. There is a single wire running from the brake pedal, twisted together without solder, running over to the auto gearbox selector.
I assume that the cut wires are redundant if the ECM has been switched to an auto one. Or, am I getting mixed up with the ECU? I have no idea. haha.
I found a post from a member of the Whirlpool forum who got cruise working: https://whrl.pl/Reng1q. He has a manual Corolla, and he had to run two wires from the spiral assembly to the ECM in the engine bay for cruise to work. I wonder if I should do the same being that I'm working with a manual harness? I'm just not too sure what to do with the clutch switch wires if they were indeed those wires. Pressing on the brake cancels cruise on an auto, so do I need to bridge that wire that was added, running to the gearbox selector? It controls the unlocking of the gearbox selector when the brake is pressed down. Any help at all from anyone is much appreciated as I will pass it onto the tech.
