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

[TcBryan]

I have found several at the local pick your part yards.

CT Scott, I will trade stalks for wire harness for cc.

Has anyone installed CCS on the Toyota Yaris 2018 facelift

where can i get ecu wire for cruise and wiring harness for clutch switch help

where can i get firewall piece i lost it

So I read through the entire thread but didn't find a solution my issue (some similar cases but no resolution).

I have an 07 sedan, auto transmission, Canadian car. I went to perform this mod today, only to find that I have a factory wire (pin 40) at the ECM connection but no wire at the D3 connection under the steering wheel. No CC lights in the cluster either. Car has been dealer serviced since day 1.

Anyone else figured this one out?

EDIT:
Found the solution in another thread. The pin 40 wire seizes to exist after the firewall connection (AD4) on the drive side of the vehicle. Weird! See attached photo. Hope this helps someone out because it sure as hell gave me headache.

Another thing I just noticed is the switches I bought Radioshack catalog #: 275-644 don't say whether they are NO or NC, Would these switches Radioshack catalog #: 275-1566, be better? I know they have to be NO switches, just wondering if that could be the problem I got NC instead of NO switches.

A 560 is probably too low. The 5% can go either way, so if you use a resistor close to either end, you really should check it with an ohm meter to verify what the actual value is. Being within the range is critical. If you are out of band, the ECM will not recognize the function.

The 275-644 switches are N.O., so they are fine.
