I first ordered the Scosche TA02B wiring harness to hook up my JVC deck. This was clearly not the correct part. I just ordered the Metra 70-2105, which looks like it'll fit.
The harness includes a red wire to be used for ACC power. Apparently this isn't part of the factory wiring harness and I'll need to tap a source of ACC power somewhere in the car. Does anyone have any suggestions on what to use?
