I'm not overly comfortable doing this stuff so printed off forums, pictures, diagrams, etc. and dropped them off at my mechanic, who know what he is doing. He intalls cruise stalk and drills hole in wheel cover. I did order cover with cruise hole already in it but was shipped the one without the hole. Another whole long story I'll save for another time. Go to pick up the car and he says it doesn't work. He said there already was a wire at connector A21, pin 40. Is this possible? He also said he couldn't locate connector D3 under the steering wheel. I am lost!

I appreciate someone taking the time to take my hand and lead me through this. I have read and reread all the forums discussing installing cruise and STILL don't get it.

If the wire in pin 40 is blue, then I believe it (some 07-08 Yaris have the wire from there to connector AD4 (which is way up high under the dash, but not the wire from AD4 to D3). If it's not blue, then he is looking at the connector incorrectly.

As for D3, it is under the center of the steering column (he has to remove the lower steering column cover to see it). It is the White connector below, with the one black wire (which is what yours will look like).
