Flat 2015 F150 cigarette lighter losing power and losing braking

[ie2special]

We have a 2015 F150 that are we are flat Towing behind our motorhome. We have the Patriot 2 braking system and the cigarette lighters are shutting off every 30 minutes which is causing us to have to pull over every 30 minutes and restart the cigarette lighters. If we don't, we have no breaking. I can't find any information on any F150 sites as see if any of the cigarette lighters are always on. Is there anything else we can do short of pulling over and rewiring in the middle of the night?

I don't know about 'middle of the night' but you will have to run a fused 12v(+) wire from either the full time part of the fuse block or the battery to a power plug you use for the Patriot brake system. It's very common to have the power outlets controlled by the ECU to prevent accessories from running down the battery. One of my cars (VW) has all outlets full time power, the other (Subaru) switch off with ignition or short time later. I rewired one outlet in the Subaru to be full time power.

If you don't want to modify one of the installed outlets to full time power, you can get a power outlet (cigarette lighter) at any auto parts store or Walmart and wire it up yourself. One wire (with fuse) to the (+) battery terminal, the outlet's outside shell must be wired to any close ground connection.

Ok, i think we can handle that. Of course, we are a day in to our month long trip. We didn't notice before we left becuase of the short trial trial runs :(

I can buy everything to do it

Bought 12v plug that runs from the battery and an extension. Ran in into the truck through the door...we will see
