Camper pigtail was cut off !!!

Most RV plugs follow a standard wiring scheme, you should be able to find a wiring diagram with a google search.

Someone will chime in to help you shortly.

etrailer , have the wiring diagrams and parts o help.

There is no industry standard for color coding for your pig tail. I would suggest you contact the mfg and ask them if they could give you the information. With info from them its time to start tracing each and every wire to verify what it is.

.. or you can get a 12V test light and with the help of an assistant draw up you own schematic diagram to avoid any possible non-standard colors.

That's the way I have done it several times..It works well with about anything that is connected to the trucks plugin.

I’m not sure some of the above suggestions are helpful in figuring out the camper side of the wiring. My advice would be to figure out which wire is the ground first by using an ohm meter. It’s likely the larger white one. Then I’d take a fused 12V source and start touching +12 to the wires one by one. One will be the left turn, one for right turn and one for tail & marker lights at a minimum. The large red one probably connects to the camper battery to charge it, assuming there is one on board. If there is a battery on board, you can also use a meter or test light to see if the battery connects to the wires.

Alternatively, look for a wiring splicebox where there may be a chance to trace wire colors by also pulling a taillight out to access the wires.

There isn’t a camper wire color standard but there is a 7-pin RV connector plug standard.
You can figure this out, and you won’t fry anything.
One of the heavy gauge wires will be the ground, probably the white one. Run a piece of wire from it to ground on your truck... the bumper, the - side of the battery, wherever.
If you string yourself a long piece of wire from the + side of your battery, you can figure out the other wires. The tail lights will all be the smaller ones. With your ground wire hooked up, touch your + wire to each smaller one and go look at the tail lights. One should light them and all your markers up.
Another should do the left turn, another the right, and another the reverse lamps.
The other larger wire will be the +12v charge wire. There should be a terminal on your trailer connector that has constant +12v. It goes there.
That will be a total of six wires, that’s all of ‘em. The 7th place on the trailer connector is the trailer brake terminal which obviously won’t be used on the camper.

You can look up online which pin should do what on your truck’s connector or you can figure it out pretty much the same way, with a 12v test light. Just see which one has power on and off with each turn signal on... which one has power when the brake pedal is being pressed... which one has power when the running lights are on... and so forth.

You are correct. I was visualizing the cut at the truck not the camper. The method that you suggest is what I would have stated had I understood the OPs dilemma better.
