I installed an alpine ILX-650 HU and by passed all the uconnect crap, but running all my own speaker wires, etc. I need a harness to retain my backup cam and it looks like this will work ( https://www.ebay.com/itm/Scosche-CR...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 ) but cant find it in stock anywhere, any other options? Thank you
