Do I need power at pin 4 on my tow vehicle?
I think y'all think I be dumb. I know I need to plug that big black rubber thing on my trailer into my truck (what else will keep the trailer from falling off the ball ;)) This year we're going to...

BTW, didn't see it mentioned...
You can install a battery disconnect and have your battery disconnected when the trailer is sitting stored at home and not plugged in. This is a good thing for battery life.
However, do not have your batteries disconnected when you are towing. The break-away brake system on your trailer requires 12V battery to activate the brakes in the event your trailer detaches from your tow vehicle.
As for active power on pin 4, you really should have that power available. What would you do if your batteries were drained and you needed to tow? Having that power available will make you legal with regards to having the power back into the batteries for your break-away switch to properly activate the trailer brakes.
