White or white/green
On the rear clearance light, which wire is more apt to be the negative wire if some one knows ! The solid white or the white/green? Problem is trailer is in the back yard and impossible to get the truck through the back alley to plug in the truck to determine which is the positive wire and which is the negative. Beautiful day out and thought a good day to run the electrical to where the back up camera is being mounted. Personally I think it's probably the white/green as negative, but not 100% sure.

It's alright, I'm going to connect a battery to the taillight and neg at the 7 pin then find polarity with the multimeter.

I think you're trying to rush the season up there.
Better strap on a pair of snowshoes just to make sure you can get back in time for supper.

Lol, Lloyd... Such a beautiful day and I have so many little improvements sitting in the garage that all need to get installed, be a shame to not try to widdle one off the to-do list. Probably can add a little boredom to the reasoning as well. But at any rate that ones complete and off the list. There's one thing that never ceases too amaze me, and I know it's not just me, as a couple other buddies say the same thing. It's amazing how every time these tiny little half hour jobs can pretty much destroy a day. 6 hours later the job is complete, but the tools haven't been put away and the back of my calves are telling me
it's been a while since I use to make a living standing on a ladder kind of thing. lol...Turns out the green/white which I thought would probably be the ground, was in fact the positive power line. Be a good one to remember for next time..

On mine, the battery negative and the water pump negative are both solid white. Think like house wiring, white is not hot, it's neutral.

All properly wired RVs always use WHITE for the ground.

I do not believe that Rv manufacturers use a standard color code. They use what ever is handy and nearby.

Maybe what you say is true, but In my experience, since 1973, I have owned 3 TTs and 6 FWs and all have used White for the ground. I wasn't looking to cause any issues, only trying to help.

In truck transport trailer all plain white wires are ground wires. But that being said, travel trailers are assembled with whatever is cheapest. So jump the plug with a fuse so that your markers are lit up. pins 3&4
then pull the bulb at your light. test with volt meter for polarity.

A little off topic, but looking at the pin wiring reminded me about a 12volt car flasher. I had a plug made up with a a car flasher could plug it in and it would flash all the running lights on the trailer. Plugged it in to a friends trailer one day without him knowing. When he came outside all his trailer lights were flashing and he was going crazy trying to figure out what was wrong. Course I did fix it for him

I did something similar as too what Miniozz mentioned. Took my small lawn tractor battery out to the male 7 pin, but used terminals 3 (positive) +1 (negative) and as mentioned used the multimeter and identified the pos and neg. Guaranteed it's fail safe.

Very helpful
This thread was helpful to me - thanks!
I had a tire blow out on our last camping trip and while changing the tire I noticed that white and green/white wires were loose under the camper. I read this thread and sure enough, they were for the clearance lights!
Thanks again!
