Trailer Wiring Question
My wiring converter went bad. I failed to note the wiring when I removed it. It has 6 wires coming from coach. Two whites I verified one white as a ground to chassis but don’t have identify for other. Photo attached. Anyone with same number of wires please advise connections.

No guarantees, but it should be as follows
Brown Tail/marker lights
Yellow Left Turn
Green Right Turn
Red, probably 12 volt charge line
Small white Ground
Large white Trailer brake wire.

Any info on where the trailer brake would receive its signal?

HI . MY COACH #547 i installed a newer style controller. on small knob to set it. on mine i called marathon and got a little info. but found two wires behind the dash panel bundled. one i think was pink 10 gauge. and the other cannot remember but was a 10 gauge. i used the pink because i traced it to the towing juntion box in the rear right side of the engine bay. the lighting wires were all in the juntion box. do you have that grey box it is labeled towing. hope this helps.

I don’t have that must be something marathon added. I have a molded junction connector at right rear next to backup alarm and just above air connection.

Hi tom
i had same control unit that was not working.Junked it and all I did was test each wire for power for left and right signals and brake lights and used a connection board to tie wires to hitch plug.Much simpler.Some of those wires I did not reuse .
If you want I can send a picturejim
