VW Radio Wiring Harnesses: Amazon I'm really happy how the harness turned out. there is 1 issue however. the accessory wire does NOT turn off the stereo. this is an issue on VW's end. simple enough, just rewire the accessory wire to either the fuse panel or the cigarette lighter. personally, I installed it on the fuse panel.
