Can I get voltage sensitive power control?
I'm putting a wireless backup camera on my car hauler trailer and I want it to be powered up only when the truck is running. So I'd like to use the hot feed coming from the truck to power the trailer ...

My trailer is buried in a rented winter storage spot and inaccessible so I can't check my facts on this. However I'm pretty sure the breakaway battery is already isolated to the brakes by a small charger like this. If that turns out to not be the case I do plan to install a diode to prevent the breakaway battery from powering the camera so all will work as desired.
