Wiring diagram for fj80 backup camera (1 Viewer)

[kangjinsoo]

Hey guys,
I’ve done some research and I can’t seem to find the wiring diagram for specific harnesses I am looking at. My ‘92 Land Cruiser shop manual doesn’t seem to show the color scheme for the wire looks either. I am trying to figure out which wires are the best to use for both a backup camera and a usb charger.

First: the backup camera wire is being run from the radio in front dash to the passenger side taillight as there is better accessibility for splicing a new circuit to the existing wire harness. I don’t know the original color scheme for fj80’s for this particular wire harness? I’ve listed a picture below. The wire harness was originally going to a speaker in the rear quarter passenger side.

Second:
Wiring up a usb where the cigarette lighter was. Just need to know which wire is hot and which is ground. I’m confused because there were a total of four wires going to it and I could not figure out why. I think based on the wiring scheme from my shop manual it was daisy chained to the clock? Not sure.

I attached pictures below of both wire harnesses which will hopefully better display what I am dealing with. I am merely looking for suggestions of which circuits to tap into and use?

Thanks in advance!

I've just added the 1992 EWD (from the Chasiss Repair FSM) to the Resources section. Download a copy for yourself. All the connectors and wire colors are listed in that EWD.

I'm not an expert on the 1992 80 series electrical system; maybe @jonheld could chime in with a suggestion or two on which circuit is best to use for your addons.

Sorry! I forgot to mention that for the backup camera I am trying to splice into an “always on” circuitry to be able to switch to backup camera while driving as well as backing.

Does anyone know where the backup light wire at the rear of the 80? It'd be a great spot to tap into the wire to engage the backup camera.

i just tapped into the reverse light globe +ve wire when I installed my reverse camera

Thank you very much! I'll get a splitter and tap into that
