DIY Cruise Control on 07-08 Yaris (step by step) - Toyota Yaris Forums

Ok Guys I tried this MOD today and it doesn't work. I used 2 NO Switches and 1 680ohm 1/2 5% cfr resistor, grounded to chasis at the drivers side door and hot to PIN 40 of the ECM. Jumpered the Clutch switch and took it for a test drive. NADA.
I'm wondering if the resistor may be the problem or if the problem could be that I used 20 Gauge solid and not stranded wire, (shouldn't make a difference I wouldn't think), to build the circuit and run the hot and ground. every thing checked and doubled checked, any Ideas? BTW, I am using the 2 switch method not the 4.
