where did you get the sw 12v power from?

 

which pin is pin 1 on the 28 pin connector?

Do you have to run wiring from the hatch to the front of the car to have a backup camera or is it already present?

 

Hello,

Does anyone have a wiring diagram of the 28 pin connector for the steering wheel and voice call control connector? "#11" from wmo168 original photo. From the "Headunit wiring.pdf" uploaded by wmo168, the plug looks to be a I150 or I155. I purchased the AXXESS TOY28SWC harness which is the correct connection, however the pin configuration doesn't match my harness. My OE harness has pins (right to left) in: 4,5,6,11,17,18,19,21,22,25,26,27,28. Whereas the Metra/AXXESS aftermarket harness (counting left to right because it is inverse to the OE plug) has pins in: 2,11,15,21,22,23,24,26,27,28. This has missing pins to match the OE connection on pins: 4,5,6,17,18,19,25. With unused pins at: 2,15,23,24.

I found a connector on amazon that has all 28 pins wired the same color (3rd image below), and can splice my own into the aftermarket head unit harness. I just need help understanding what all of the pins go to? Any help will be greatly appreciated. I found the last image which seems close to what I have but still has mismatching pins, 15 & 23. I think that is the best so far to start from if I have to trial and error test what each wire does. I was thinking worst case scenario plug the 28 pin pig tail connector in and hold a test light onto the wires and start pushing buttons on the steering wheel to see what does what?
