So I fixed the bad wires and replaced the plug. Still nothing. Dash doesn’t recognize a trailer. Trailer lights are good because they work with other vehicles. Still getting B1C57-14 (2F) among some other odd codes with a slight lag in starting the truck. None of this was happening prior to initially plugging in the lights. Thoughts?

 

LED or filament bulbs ?

 

Both. Tail lights are LED and side lights are filament

 

Then you need resistors so the car detects a trailer and stops the rapid blinking and relays to stop the pulsing..

 

Sorry, not sure what you mean. Nothing is happening. The lights work fine when I hook up my ford pickup.

Could this error code have something to do with it?B1C57-14 (2F) Passive start ignition relay coil circuit - General electrical failure - circuit short to ground or open

 

Code is not related to your trailer, trailer wont be detected due to the LED's so needs resistor to put a load on that can be detected. The LED's will flash fast and oddly due to the vehicle sending pulses down the circuit looking for a trailer.

 

Thank you. But there are no lights at all, fast blinking or not. Does this still indicate a resister is needed? And how would I go about installing a resister?

tks

 

Yes you will need them but first you need to work out why they aren't working, most likely a wiring issue on the car since the trailer lights work on another vehicle.

 

Have you confirmed that there is power at the plug on the car? I don't recall the pinout right now, but on the 4 pin ground should be different that the other 3. From there you can turn on the 4 way flashers and check for power for brake / turn signal and turn on headlights for the marker lights.

Hope this helps

Tks. I’ll take a look at that.
