The braking system has to be powered by the dinghy/toad - or it won't work in a 'breakaway'...
The toad battery should be kept charged by the RV feed.
The 'normal' (there ARE variations) pin convention of the 7 wire connector includes a continuous 12v feed from the RV... shouldn't have to run an additional wire.
Not familiar with the Patriot specifically... I use Invisibrake - it has a direct line to toad battery (battery disconnected from rest of vehicle in my case for flat tow) - as well as to the RV trailer wiring harness of power (12v continuous feed) and brake light and charges the toad battery from the RV feed...
(I did need to run an extra wire for the monitor light on the dash of the MH... that has a connector right by the 7 pin harness for a single wire from toad.)
Everything stays happy and charged when connected - and if ever needed - the brakes will engage for a breakaway.
Using a direct connect to toad battery rather than ignition in accessory will limit the battery draw to the braking system only - but ideally want to be charging the toad by some means.
Looks like newest Patriot (BRK2010/2012) includes a battery according to their website... "Built in battery ensures power is always available to the brake."
