Yup. Orange wire, top right terminal in the connector as you look from the back.
But... its fed by a relay that is only on during key hot. They do that so you can plug in, run the truck and charge the battery in something like an RV, but then if you shut down and the RV is draining juice, it won't suck the truck battery dry with it.
You can bypass the relay two ways. supply a small hot wire to the small side of that relay with a switch so you can kick that relay on at will, or bypass the relay with a big, fused 10 ga wire
