location of rear hitch harness blue wire that has 10 AWG (UL) GXL on 2018 Thor Vegas

I located the brake wire, +12 V, and ground for my brake controller.
I am unable to locate the rear hitch harness blue wire that has 10 AWG (UL) GXL written on it shown on photo hitch-harness2.jpg
In the folder are the photos I took of the hitch harness and the harnesses under the steer wheel and inside the dash board cover.
I did not see the hitch harness blue wire that has 10 AWG (UL) located under the seat.
I did trace the hitch harness blue wire to a wire bundle that entered the left side of the driver above the left side wheel well, but I could not locate where the wire went after that.
If anyone has located where the wire comes out inside the cab could you please let me know and/or show me a photo of it?

Hiya, you don't mention what model you have, you may want to add it to your signature. I, too, would like to know the answer. I suggest you call Thor Customer Service, don't bother with email. Have the last 8 digits of your VIN ready. Ask the rep if they can explain it (please share back to the forum) and ask them to send you any and all pertinent construction drawings and wiring schematics (PDFs). But ask for the plumbing diagrams too. I just looked at the drawings I have but I don't see a harness to the tow receptacle, sorry. Good luck.

I'm wearing trifocals now but my hindsight is 20/20.
Bilsteins and Sumos front and rear...HUGE! FatMat and Hoodliner...HUGE!
Hellwig sway bars F&R, 235/85 Hankook ATM, alignment...HUGE!!!
Battery watering, 260watts Solar and BigFeets to make life easier.

IF your coach is on a Ford F53 then take a look at post #7 of this Forest River forum.

It's from 2008 but a F53 in 08 is going to be pretty must the same in 18.
