    I bought a wireless backup camera that I plan on splicing into the rear center marker light. I removed the light and noticed that there are two green wires and two white wires that go into 2 crimp connectors but only one of each wire is connected to the light. I am by no means an electrician, what is the purpose of the dual wires? Would I be able to split them up so one pair of wires goes to the camera and one to the light?

    If anyone is interested, here is the backup camera I bought:

    It's just wire going to the next marker light or tail light. Just tap in somewhere and you'll be fine.

    I assume you want the camera on whenever the marker lights are on?

    does the rear center marker light have power when you back up?

    When I had a popup and had the wireless backup camera , I tapped into the 12 volt supply to the fridge, that way camera was always on and was used as a rearview camera.. So far I never have gotten it wired up on the TT..

    On my TT its wired like that. So, you turn on the running lights and can use the camera while your driving. Nice to help when changing lanes. Tbh, never used it backing up.

    Ah, that makes perfect sense, not sure why I didn't think of that. Like I said, I'm not an electrician by any stretch of the imagination.

    And yes, I must have the running lights on when I want to use the camera. Thanks everyone for the replies.

    Does you trailer have a backup wire? My Coleman Chesapeake PU has one. In fact I wired two Eagle Eye LED backup lamps into it, it was the Grey wire. If you connect to the marker circuit your camera will be ON all the time your marker lights are on. Of course my Coleman Chesapeake came with a 7-way RV connector and your trailer might only have the 4-way connector. Just use one of those 3-M connectors that will go around one of the wires and you insert your new wire in, then push the metal spade in and close the plastic cover. 3mtm-scotchloktm-instant-auto-electric-connector-804.jpg

    Yes, you can, and that is how all of them are wired on Travel trailers. Just remember, the white is ground, the other is power. And power will only be on when you have all of the marker lights turned on. I wired one on our 2018 Coachman Clipper. I think that the positive wire was yellow, and ground was white. In any case, a voltmeter is your friend.

    I have a light on my licence plate to which I wired my backup camera.
