Both 6 and 7 pin coonectors should have a "charge" line. Your trailer connector should bring that line the the TT battery, but the connection on the tow vehicle also needs the heavy gauge line to the alternator. Usually comes with a factory tow package.
Just because the pins are on the connector, doesn't mean there is apprpriate wiring to the pins, particularly pins dsignated with alternative uses.
Thats why I was thinking that my current setup probably did not have a charge line. My jeep does not have the factory tow package, which from the Jeep's I've seen that have it, they have 7 pin connectors. My hitch and everything was installed by Uhaul so I only have the 4 pin of course.
