Can anyone help? Car is a facelift 04.
Which end are you asking about? Inside the steering wheel, there is a 4 wire connector and that does both the radio and cruise. At the bottom end you have to run 3 wires (using those from the cable set). 2 go over the the LCM switch (power and i-bus) and 1 goes into the engine bay for the cruise control.

Did you download the pdf file in post #10? It and the pictures should get you going.
