Rear Camera Installation for a 2014 Minnie Winnie

[Harpoon-WO]

I am trying to install a backup camera on my 2014 Minnie Winnie and I want to tie it in to the running light in the top center in the rear. I notice that the running lights have 2 white wires. How do I figure out which one is the positive wire and which one is the negative one? I also want to install a new bracket where the bulb is because the plastic is cracked. The new running light has a black and white wire, and the camera has a red and black wire, so I want to connect all the positive and all of the negative wires together.

Hi Harpoon-WO,
I would buy a good Multimeter to check for voltage and polarity. Here is one on Amazon:

Thank-you. I should be getting 12V DC on the positive lead?

With the red lead of the multimeter on the positive wire, you will get a "+" sign for the voltage.

It is odd to have 2 white wires from a fixture like that. Some of your lights may be connected in series. If you remove the bulb, do other lights go out? If so, either white wire is hot and just connect your ground to the frame. Be sure your camera does not draw too much power or the lights will dim which is real bad for some LEDs.

The white wires are probably connected to the chassis wiring in the wall, the rest of the running lights are all connected in parallel in the wall!
