I have a U.S. FJ60. I picked up a 12 Volt OEM Inclinometer from Oz. Has anyone done this installation? Is there a direct plug-in on the wiring harness and what needs to be done to the dash to fit the unit? As well as angle guages, it has a clock and light which I suspect will work when wired. If you've done this install, I would appreciate your help. Thanks, N.M.
