I just bought a setup off another member and might try to do it myself. I will attach photos so it will be easier to understand what im saying. Right now i dont know where the 5 wires that come out of the power on the brain go.

ok so i found out the

White/green wire are for a rear view camera
gray wire is for parking brake lever
and red it power

Whats the black for? ground? Where can i hook up the red, black, and gray wire?

Not postive on this because I don't know what brand/model you are hooking up, but chances are:
Red = 12 volts constant or (may be 12 volts ignition)
Black = ground
Gray = e-brake wire, which you could just send to ground with your black if you want to be able to use the screen even without the e-brake on. Otherwise, it is supposed to be hooked up to the wire that gets a negative signal when you pull your e-brake up.

All of these wires can be found right behind your OEM radio/cd player or even at your main ignition column. NOTE: If you go to the ignition column for power/ignition, make sure you fuse your power wire that you run over there.

Thanks yea i found out that the gray can be hooked up to ground also. Im probably going to use the wires behind the radio so its easier for me.
