7 pin plug question
I have my new FW and was wondering when parked over night say in a Walmart lot with no power source do you leave the FW plugged into the truck and does it draw off the truck battery?

- Flip open 7 pin receptacle cover on truck and test for 12V at 1 O'clock blade.
Truck key off.........no 12V------no drain on battery
Even if there is 12V power with truck key off........overnight stop should NOT drain truck battery unless trailer battery is really low/bad
Boondocking-----YES unplug - Agreed Ford factory wired do not because of relay.
- Most factory wired Ford connectors are powered through a relay that disconnects when the engine is hut off. No need to unplug!
