Fusion backup camera and wiring
I know this has been discussed a number of times. I am just overloaded with reading and watching all the different scenarios about the pre-wired wirings on 5th wheels. I admit I am the dumbest person for electrical, volt meters, 12 volts system ,etc. I watch Youtube and they must all think we know everything about volt/ohm meters etc. They never show how to do the testing for positive wiring, negative wiring etc, so here is my wordy issue I need to know.
I have a furrion backup/observation with 4" monitor. I pulled out the center small round light on the back of my 5th wheel (2016 North Point 341RLTS). I have a white wire from the light to a white wire of the RV, I have a green wire from the RV spliced to a black wire that feeds the light, I have a blue wire that is looped that I assume is the power for the backup camera.
I exposed the existing wire splice for the white wire and the green/black wire. I took my meter and put the red lead from meter to green/black wire and the black lead to the white wire splice. The meter didn't read anything or maybe a negative. I switched and put the black lead from meter to the white wire splice and the red lead from meter to the green/black wire splice. I read 12.38 or something like that. So I take it that the green/black wire is the ground. I then put the black lead from the meter to the blue wire splice (think it is power supplied for future camera) and the red lead from the meter to the green/black wire splice and it read 12+ volts. So, my camera wiring should be connected as follows; the red camera light wire to the green/black RV wiring, the black camera wire to the blue RV wire. Please don't get discouraged treading as I am at wits end. Help me if you can shine some light. If you want to talk and walk me through it let me know as I am trying to fin fish up the connection tomorrow. Thanking for taking time to read this wordy post.
