Hey Don, thanks for reaching out!
A lot of trucks around 2020 starting coming out with "improved" wiring systems that just became major hassles for owners, as you're experiencing.
To bypass all of this you'll need to run a 10 Gauge Wire # 10-1-1 through a 40A Circuit Breaker # PK54540 to send power directly to your 7-Way 12V power pin actively.
Let me know if you have any other questions!

Hey Don, did running the 10 Gauge Wire through the 40A Circuit Breaker help solve the charging issue with your trailer batteries? I'm curious to know if this solution worked for you, as it could give others confidence when dealing with similar problems.
