update:
yes, the rear cd changer should have accessory power. However, you need the stock radio for that to work. The crazy circular connector for the CD changer goes straight to the extra 2x5 connector that plugs into the back of the stock radio (and not into the replacement harness).
I ended up getting a 6 cd changer and using the normal power connector for it, and using 1 wire in the circular connector for switched power. I added a relay, so all the power comes from the big power connector, and the switched power only drives the relay.
on the radio end, I hooked up the radio's remote line (it's blue) to the correct pin in the cd changer connector (I used the green wire, I think that's the stock acc power wire, but not sure). Now I've got a switched USB port in the back of the car, and I'm using it to power my dashcam.
I mounted the dashcam to the rear window via a piece of plexiglass. The plexiglass is stuck to the rear windshield with some adhesive pads (between the defogger traces on the windshield, not over any of them). The dashcam suction mounts to the plexiglass. |
