12v charge wire
Not having the full factory towing package and not being able to locate the factory wiring I had to run a 12v trailer charge wire from scratch.
i used 10awg wire from the battery post to the plug in the back through a 20amp breaker.
there is no relay to turn the wire on/off. Just the breaker to protect the wire.
any problems with running direct to the battery in this manner? I’ve seen a few trucks wired this way in the past and have never seen an issue, but I thought I’d ask.
i really wanted to tap into the factory circuit, as all the fuses and relays are there, but it’s location is not easy to find.

It’s the 2014 expedition.
i agree a relay would be best, but I’m short on time and locating wires on this thing has been a nightmare.
I think long term I will look for a better solution, but for now if it doesn’t represent any inherent problems, I’m going to run with it.
If I have any kind of load in the camper I will unhook the plug to be safe.

No problem with doing that but like @ford390gashog said it could kill your starting batteries, especially if you are in a parking lot for a few hours and something in the trailer kicks on. Also without a timed relay you could also pull from the trailer while starting and the breaker may not catch the jump in Amp's fast enough to protect that wire and connector.
