Adding dedicated TV charging power wire

I know this general topic has been discussed previously but I cannot find much detail for the back of the TV. I am adding a dedicated 8ga wire from the battery to the back of the TV to increase the available power for charging the TT batteries whilst underway. It will be solenoid protected but what have folks done at the 7-pin connector? Do you cut in and run the 8ga directly to the positive pin, or tie it into the 10ga in the pig tail, or run a separate dedicated plug like an Anderson? Similar question and options on the TT side itself. Thank you in advance for any wisdom and experience shared.

I used the 7 pin plug wiring. I installed the circuit as an emergency source of power for a worst case situation. Maybe because I have dual isolated 12 volt batteries I've never had to use it. My solar has always being more than adequate.

If you're installing it for similar reasons, emergency use in case you end up with no battery power at all, I'd just tap into the 7 pin.

If you're wanting to use it for high draw situations then my view is that most automotive alternators and regulators aren't suitable for that. There are high output alternators and adjustable regulators suitable for that purpose but I've never seen the need to go that route. In that case a heavy gage wire all the way would be suitable.
