Brakes are not to be wired up to an ignition source, they are always hot.. brakes are to always be functional regardless of the status of the ignition for safety reasons.. The Brake controllers will go into their own standby mode after a while of no usage, and consume practically no power until you start pushing on the brake pedal.. they wont drain your battery, there is no need to unplug em.. If they are self calibrating 3d accelerometer based brake controllers you are going to lose its calibration and wont have proper brakes each time you hook up a trailer.
Ok Thanks dreadlocks

I leave my brake controllers plugged in in both Q7's. The TDI has the Hopkins Insight and the 3.6 has the Reese Towpower cheapy. Neither car has had issues, even when they sat unused during March and April.

Ordering the p3 and wiring harness from eBay for a 2013 q7. Curious if should order the harness with or without the relay. Does the relay turn the brake controller off when ignition is off or just better reliability?
