This is my first instructable and I welcome all constructive criticism.
A while back I bought a cheap DVR from China for my car. Well it lasted about a month so I guess I got what I paid for. I decided to get a true DOD DVR and tracked down their distributor to ensure I do not get another knock off. I am very happy with the DOD, the picture quality is much better and the camera is working flawlessly. I decided that it is time to wire it into the car properly. Usually the usb cable is pushed under the headliner but you still end up with the converter sticking out of the cigarette lighter. While visiting the various Subaru boards I learned that there is a power supply harness for the rear view mirror accessories. It turns out that almost every Subaru has the same power supply behind the map light pod.
The following is a very simple way wire in power for your DVR or any other accessory you need power for.
12v to usb adapter
inline wire connectors
flat head screwdriver
wire harness from old computer power supply
First step is to remove map light pod. Start by using a flat head screw driver to take off the clear cover of the map lights. Be careful not to scratch the pod. You can tape over the screwdriver to prevent scratches.
