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?

 

Did you ever find out what each plug is for? I'm looking all over the net and I just can't find it.
However, I do know plug 6 and 7 come from from 11. I think those are none-speaker system wires like
