Trailer 7 pin junction box and connecting wires to new trailer brakes.

[@Oldtech51]

On a fully welded trailer frame there isn't any reason to run a duplex wire to the brakes. A single 12 gage wire is sufficient. Crimp a marine grade eyelet on the other brake magnet wire and ground it to the frame. Not the axle. You cut down the length of wire by half. If the trailer frame is bolted or clamped together then a separate ground wire would be best.

Thanks for your time making a video appreciate it. Question do you put either the white or the black wire for the brakes on the ground terminal thank you.

@@westonlee9778 You’re welcome man. Hope I answer this correctly. On trailers I treat the ground as white. I don’t think it is polarity sensitive at the connection at the drum.

Is the green wire- right turn, yellow- left turn, brown - running lights, and blue- brakes?

[@burksgarage]

@@mrgoodtimes05 correct

Universally its suppose to be some companies use different colours, so always check to make sure.
