Here's my back-up camera list...
for the price of the Beatsonic adapter, you can almost get the harness AND cam!
I installed both over the weekend taking it CRAZY slow. About 4 hours.
Most of the time was spent fishing wiring. The only thing you'll need apart from a 10mm and 8mm socket wrench is a wire crimpers/cutter (about an $10 part) and a drill.
The kits below come with everything else you need (wiring, connectors, drill bit, hole saw).
This kit includes the power so no need to tap anything. The only hitch is you need to find a ground wire. Easy to tap into that.
1. Back-Up Camera Wiring - $34

UPDATED 1/9/15:
Heads up guys - as I was thinking about this post, I left out some details.
1. You will ALSO need about 12 feet of positive wiring and 3 feet of negative wiring. A few bucks from the hardware store. Use like the 18 gauge thin wire. You'll need this as the kits don't give you this.
2. A U or O shaped connector to hook your ground wire to and bolt to the amp ground
3. For the back-up camera, the BOYO VTB I mention below is only 170 degrees and is a fixed mount. So this only shows about 8 feet behind your car. If you are looking for cars coming at you from the side, shoot for as close to 180 and wide angle / fish eye with a tilt option. This may cost more. I did a SONY rear camera and that was $100.
