Need suggestion for trailer wiring
I've tried running a search and have looked back about 8 months but can't find a thread addressing this. How would you suggest charging a TC house battery with the 7 pin connected to a cargo trailer ?

First off, have you verified that you have 12 volts to the aux pin?
Many manufacturers dont have the fuse in place to energize that wire.
Check the voltage before modifying, it wont be a lot, but you should get some charging even with the existing small wiring.
Also if you do decide to increase the wire size, verify that you have at least the same size ground lead.
