I have installed a new cruise control switch and connected the wiring (my harness was not wired for it) - red wire to pin 40 on the ECM, black wire to earth. I checked the end results with a multi-meter and both checked out for continuity - switch to ECM. I also got the Toyota dealer to verify the existence of the cruise control on the ECU on their Techstream software. They confirmed it was there. Still my cruise control will not work at all - no light or function. I even checked the new switch to ensure (with a multi-meter) the resistance was different for all switch positions. Just don't know where to go from there. Anybody got any ideas?
