Hi NIBS,
Mate I just hooked up mine tonight. I mounted my camera on the inside of the small door at the top. Just used a couple of self drilling screws, so it should hold for a while, corrugations would be a bit of an issue, but we won't be on any of these for a while.
As for the wiring I ran the positive wire from the screen to a cig plug, (so I can turn it on any time. The camera is not an infra-red camera, but the vision is still very good).
This plug then goes into a 4 socket power board that I made up that is velcroed to the centre console on the passenger side. (this board is only used for phones,gps etc as I have two sockets on the back of the centre console wired with 6mm through a fuse block and to the aux battery under the bonnet for anything that needs a bit more)
The power for this runs from the standard cig plug near the sub tank switch, so it only comes on when you turn the key to accessories or start the patrol up.
I mounted the screen to the pop up door near the top of the dash. This little hidey hole will not be used as it will have two little screws securing it shut.
Hope this helps
Greg
Sorry NIBS I should of said that we have a patrol also.
