Check your owners manuals for the right relay and which slot it goes in.

I knew I would get the right answers here.
My owners manual for 2013 F150 does not show a relay installed, so that answers that question. New question: Relay Part Number?
In my 2020 F250 manual, it does show a 30 amp fuse for Trailer Tow Battery Charge. So that’s good news. I’ll verify it’s actually working when able to swap trucks around.
Thanks for the quick responses, Chuck and Rob.
