New body style + tow charge relay
On my 2013 I learned - after almost full season of towing - that there was a relay I had to installso that the truck would charge the camper battery while towing.
Looked high and low on my 2016 and can't find it, does anyone have a 2015/16 and know if the same relay needs to be installed?

The wiring diagrams in your Owner's Guide shows where the fuse and relay are to be installed. It's in the "power distribution" box under the hood, not the fuse box in the passenger's kick panel. Mine works fine.

Here's a thread that discusses the issue/question: https://www.f150forum.com/f118/7-pin...harger-288637/
In summary, the 2015/16's no longer come with the tow charger relay and fuse like 2014 and prior model years. The truck will send power via 7pin so long as it detects load (resistance oriented). There is also mention to 'enable' power sending, the truck brake needs to be pressed once and/or slight rev (no trailer charging during idle)
