I have a ‘16 C1 that I’ve installed Cruise control in, but I do not know where to put the Single pin wire that goes into the Ecu harness. So stock is in, plugged in, grounded, but that last piece is completely unknown. If anyone has info or even better a picture of the location for that pin connector I would be ecstatic, and I’ll make a detailed video on the install process for others in the future. Thank you!
You can find the instructions by looking around on the Rostra website. Their kit is the most expensive I've seen, but some of the cheaper ones come without any instructions at all. Pay close attention to the instructions, the location to plug into the ECU changed with the 2016 models. I think it was previously the lower left corner of the ECU, but changed to the lower right. I will look for my copy of the instructions and if I find it I'll post a copy.
