Pulled pigtail off trailer

[Amoroso6]

SO with lack of communication when I pulled forward to unhitch the pigtail came with the truck UGHH. SO i'm trying to reconnect the pigtail to the trailer, 2019 coachman chaparral 381D. i cant find a schematic that identifies the wires in the junction box on the trailer. They are White (which i assume is ground) White with a blue stripe, Grey, Brown, Light blue, Dark Blue,and red. now these dont exactly matchup with the pigtail in colors so I need to Identify the trailer wires so i can reattach. hopefully these pictures will upload.

thanks but the wires coming out of the trailer dont match the colors of the pigtail.

7 wires. Decide which is ground on the trailer. Now move a 12v source to each wire see what lights up. RH stop light LH stop light, running lights, brakes apply. that's 4 of 7. you know the ground wire 5 found, see which goes to the battery 6 found, and the last is the Aux wire.

This is your best option. Wire colours aren’t necessarily standardized unfortunately.

has the answer for you...
the color coding from etrailer dot com website allows you to ID which wire is which at the plug end...

is going to take a bit of work on your part, since the color-coded wires ripped out of the trailer harness...

it won't be that difficult to ID the wires... someone watch the lights while you jump 12 VDC to each individual wire, then mark the wire with a Sharpie pen with stripes, and corresponding sheet of paper... 3 stripes on the wire=left brake, 4 stripes on the wire=right turn, etc... Then mark that sheet with the corresponding color code of the wire from the pigtail using the etrailer picture.

Of course this would be the perfect time to get one of these if you weren't on the road.

^^^^^^^^ x2. I may go ahead and order 1 of those. The connection with 3 or 4 wires in it is probably the ground. Find your hot wire on the trailer end and see what lights up on each wire and label it. Trailer cord is color coded as to where each wire goes. Good luck.
