Re: Trailer wiring question
without knowing how many wires are on the device, its hard to say. make a
custom plug, take your trailer wire on your vehicle, isolate the brake light wire and run that and a ground to the device you are using. the tailights have 2 light bulbs. one for blinker and one for brake. find that wire, from each side or one and use it. and a ground.

Re: Trailer wiring question
'My' Jeep, which is like his 'Wrangler' only has 'one' bulb and 'one'
filament for brakes and signals which requires a logic circuit to separate/consolidate the signals. You seem to be 'full' of good advice (not).
