its a straight job, will take you an hour max.
You'll need to take out HU, and some trims.
Feed the RCA cable down the trims along the length of the car.
Drill the hole and insert the camera.
Use cigarette lighter for power(if you have one) if not than run another set of wires down the car. RCA being driver side, power being the passenger side.
Thats it really, in a nutshell. hope it helps
