Question:
I have a 2019 Ford F250. I only have power on pin 4 when the truck is running. Is there a way to have 12 volts at all times when the truck / trailer are connected? I dont want to start my truck whenever I turn on lights inside my trailer.

The power to the 12 volt pin on the 7-way of new Ford trucks like your 2019 Ford F-250 is unfortunately a common struggle so you're definitely not alone but thankfully there is a pretty simple solution.
All you need to do is run your own 10 gauge wire # 10-1-1 (sold by the foot) from your 7-way through Circuit Breaker # 9510 and to the positive post of your truck battery. This will resolve the issue of you having to start your truck just to turn some lights on.
