well, the cam should have a single RCA wire for video. you SHOULD have a backup cam input on the headunit, you will have to consult your wiring manual on the exactly which one to use....as for the power, you can tap the reverse lamp wire for 12v power and ground the other wire where ever it is feasible. That being said, if you are going to ground somewhere under the truck, i would seal the grouding point with a heavy coat of Corona Red-X.

Here is the link for my head unit.I need to see how do i wire it to make the screen automatically change to camera view and overide whats on the screen when i shift into reverse.

i would use the dedicated video out RCA. Now, when you tap the reverse light for 12v power, the cam will come on and send signal to the headunit....there should be a simpl option in the functions settings on the headunit for it to come on.
