@Bart83 very nicely done, wish you did it before I started last year(and still haven't finished)!
My main battle was to run the wire from the brake pedal to the ECM A41 pin. I did it last weekend, had to go through the passenger door harness, and under the dash board. Mine is a right-hand side steering wheel, so the harness looks slightly different to yours.
Also mine is a CVT transmission, and probably need to do something in addition, because it still doesn't work
AFAIK the clutch pedal signal in my case will be a GND signal to pin B29 of the ECM!? If I measure the pin(with the battery disconnected) I get around 10-15 Ohms to GND in D and S positions, and infinity in P, R, and N positions. If I ring the wire from the pedal to A41 I read around 1 kOhm to GND(reading from the ECM), and infinity when brake pressed. So this wire supplies +12 V to A41 when brake released.
I described in previous post my wiring from the new steering wheel buttons to the GCM module.
When Cruise Main is switched on, the light comes on. But if I drive over 60 kph and try to engage CC(pressing the Set/Decel button) nothing happens.
Has anyone ever had a firmware with CC disabled, or am I forgetting something, or my wiring is bad?
Will listen to any suggestions, and update when/if I get it right.
