Wiring help for the mechanically challanged

[bonzaiii]

O.K, I'm trying to install my back-up camera-Yes I'm still working on it. I have mounted it on the far left side of the dash next to the drivers side pillar. Now I need to power it. I just have no idea what wire to tap into. Any suggestions would be most welcome but please remember I am truley mechanically challanged so the easier it is to find and get to the wire/connection the better. Thanks so much in advance
