Rv Trailer Plug Wiring

[JWH]

Does anyone know the correct configuration of the wiring for the trailer plug
The way jayco wired it up nothing works on the toad. They configuration in the manual is the standard rv configuration. How jayco has it wired is totally different
I have a 7 way rv led tester and all I can get to show working is the 12v power and the running lights
Cannot get brake and signal light led indicators to show
Almost as if the is now signal coming from the
Wires
Is there an in-line fuse somewhere
All the fuses that I checked are good
Help

There would not any inline fuses and normally the wiring harness that JAYCO installs is "plug and play". There are probably separate fuses for the trailer wiring(right & left) in the chassis fuse box.

Yes your correct usually they are plug and play
Not this one, I think someone at the factory decided to
Have some fun
Where would the chassis fuse boxes be located
Thanks Joe
