Re: Trailer wiring question
You bought a device that is looking for a system that has a turn signal
separate from the brake lights. You need a device that connects to all of
the wires, then can isolate via diodes the turn indicators and use the
signal to the brake lights.

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
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.
