Looking at both of our photos, I'm a little confused. Looks like there are more wires going leaving the junction box than there are arriving at the transfer switch!

This is how I think it should be wired at the transfer switch:

White = neutral leg 1
Blue = neutral leg 2
Black = Hot leg 1
Org = Hot leg 2
Bare copper = ground

I did not separate all the wiring in the junction box, so the photo is a little confusing. My trailer is at the dealer for service and I won't be able to verify the connections in the junction box for a week or two.

Of course this is no guarantee they used the same cabling in our units; probably did, but not a 100% guarantee. Your colors might be different.

Be very careful, you are dealing with high voltage. Don't fire (maybe literally) anything up until you are absolutely sure. I can do some more checking but not till I get my unit back.
