A Key Point for those wanting to use Brake Buddy or similar Brakes in Boxes. When we had "Lighters" then we had large fuses 20/25 Amp, and decent wires to feed them. I think they were usually "Hot" even Key Off.
Now that we have "Accessory/Convenience Outlets" we get 10 Amp fuses and wiring better suited for a doorbell.
So... For Brake Buddy, call Tech Support and let them send you a Kit that gives you 20 (maybe 30) Amps full time. Keeps BB's from failing on low voltage.
