Trailer Wiring

[Kurt Horvath]

Curt,

Looked at photos, Nice job! I am confused why did you have to make
an entire new set up for the trailer plug? Origonal wires not
fuctioning or not up to spec? I have been reading the posts and I
don't recall how this all came about.
I am also very interested in where you ran the new wire loom thru the
coach. I have been planning on this just to get more wires from the
dash to the engine compartment, for future potential up grades.
Thanks for your time
