Trailer power wiring help
I just bought an '82 Bronco (302, 3.50 , auto 3spdfor pulling my toyhauler (22' Carson). I'm on the last step of getting it ready for towing (completed: suspension upgrade, trans cooler, new brakes and master cylinder) I'm now running the trailer wiring and everythings connected to the 7-prong RV plug except the brake controller and the power (12v to charge the battery in the trailer). I can't find a place to splice the 12v in after the ignition so that it's not 'hot' until I turn the key on. I'm going to connect my Prodigy brake controller directly to the battery with a 25amp auto-reset breaker.
The Chilton manual isn't very clear and I can't figure it out visually.
Any help would be appreciated.

If you do not have the factory tow pakage, which includes a trailer battery charge relay, I would buy a battery isolator unit for trailer battery charge. Most auto parts stores sell them for under $50.
