I'm in the process of wiring in the Tekonsha P3 trailer brake controller to add trailer braking for a race trailer. I've got it all hooked up, but have a question about powering it.
Since it wants a 20amp circuit I didn't want to tap into anything existing. I used an add-a-fuse from the glovebox fusebox, but no matter what I choose it looks like everything has constant power. I'm looking for switched power so it is only powered while the key is in 'on' position.
Any tips from how others have powered a trailer brake controller before? Safely/properly is what I'm looking for, I'd be willing to change how I'm doing it.
