Wiring Furrion camera ipo marker light?

Having problems making camera hot. I removed one of my top rear marker lights and it had two black wires going to a white wire and a black wire inside the RV. The camera has red and black wires...I assume the red is positive and the black is negative. I guessed the white was positive and the black negative and connected them. No power so I reversed them and still no power. The marker light worked and all of the remaining marker lights work. The camera wires are very small (less than 22), but I feel I got a connection. What am I missing? Any ideas? Thanks!

You guessed wrong.

RV "12V" systems typically use the same wiring scheme as home 120V wiring.

120V wiring your HOT wire (the one with the circuit breaker in circuit) is BLACK (or any other color except white or green) and the WHITE wire is NEUTRAL.

SOOOO, in the case of RV 12V wring the BLACK wire is (+) 12V and the WHITE wire is (-) 12V (or battery ground).

You had a 50-50 chance of hooking up wrong..

However, rather than guessing, you should have used a "multi meter" set to DC and voltage range at 20V as a minimum to CHECK to see if you have voltage AND which wire is pos and which is neg BEFORE you attempt to connect something that may not appreciate reverse polarity!

Never guess when it comes to electrical, always use a meter first before connecting, it can save you a lot of time and money. They are dirt cheap ($5-$10) and often free with coupon at Harbor Freight.

You most likely have ruined the camera by applying reverse polarity to said camera assuming that you DID turn on the marker/running lights with the camera hooked up incorrectly (which the maker lights WILL need to be turned on ALL the time for your camera to work ALL the time)..
