Any thoughts as to where I could source a wiring diagram manual for my 2019 4Runner? I'm trying to trace out a possible fault in my trailer brake controller circuit. Youtube has a ton of videos on installing brake controllers but not so much in the vehicle circuitry. Appreciate any help that's available.
