I replaced my factory head unit this weekend with a Sony AV 64BT and I have a back-up camera that I am planning to install. I went ahead and plugged the video feed into the back of the unit and have it coild up beside my glove box. My question is about power to the backup camera. Can I tap into the 7-pin connector? If not, where is the best place to tap into? Photos or wire colors would be greatly appreciated!
