Review on Optimized Wiring Harness: Metra 70-2104 for 06-Up GM Radios by Jorge Toussaint

Suitable for my 2010 Pontiac G6. For some reason finding a wiring harness for the new G6s is very difficult. But that's all! Note the note, there is no ACC cable in this harness, but it is provided separately in the package. Connect this wire directly to the aftermarket ACC wire, then use the included fuse tap to connect to the ignition powered fuse. It took me 30 minutes to figure out which fuse to connect it to in order for the radio to turn on when the ignition is turned on and turn off when the key is removed AND the door is opened. I used a 10A fuse for the seat heater, works like a charm.
