Apologize for the LATE late bump/reply.. As far as people wanting to know what wires, I believe it was a grey/purple or purple wire in the center sunroof console.
Unfortunately after invoking lemon law on my 2014 SHO and attempting to hardwire again in my 2016 SHO, i couldn't find an adequate 12V keyed source on that harness. :bangin:
Edit: Found that the purple wire(keyed 12V) connected to the camera worked for me.
