2019 320s Boondock Edge. Trying to connect the existing backup lights to the 7 pin so they come on when TV is in reverse. They currently operate via a switch.

Does anyone know the location and wire color of the wiring for these lights? I’m good on the J box side. Just need the other end.

    @crosstrnr, I can't answer your question (although the usual standard color at the seven-way plug connection is yellow, but I have also seen purple), but I am curious if your 2019 320 S came with reverse lights from the factory.  Mine did not, and I am not aware of any having them in that model year.  I am also curious where they are located.  Maybe you can post a photo.  Thanks!

    Thanks, @crosstrnr, I now see what you are referring to............the lighting included as part of the Boondock Edge package, which I am familiar with, but did not purchase.

    Should be the center pin coming off the 7 pin connector. Not sure it's actually connected to anything in the junction box under the tongue or for that matter, tow vehicle.

    Can you look at the back of the switch and check the wire color there?

    Nice,  I have  not seen that before.   Is it factory or (previous)  owner installed? 

    As for the wiring, switches must be connected to the Fuse Panel.
    My guess is; You would need to run a new wire from J-Box to light side of the Ext Rear Switch.

    Just a thought but I prefer the manual switch backup lights the previous owner (@Dalehelman ) installed. Otherwise if you're pulling forward  trying to adjust the angle you don't see when the trailer is lined up.
