Trailer tow plug wiring

[Dakota]

I have a 2021 Ranger Lariat Tremor with trailer tow.

Can anyone tell me if the wiring to the plug for trailer lights has separate fuses?

my brake lights and directional signals work just fine.

the running lights don’t work at all.

thanks,

Check fuse #71 - its on the bottom side of the (BJB) Engine Bay Fuse Box.
You have to remove the BJB to get access to the bottom side of it.
There is also a (Park Lamp) Relay on the top side of the BJB

Did you figure out your running light problem? I have the same thing on my 2021 XLT with the trailer tow package.
The odd thing is that I have supervisory voltage of about 2.7 volts on the Brown lead/pin/wire which is the running lights.
ChatGPT suggested disconnecting the (-) negative battery lead for 10 minutes to reset the control module or reset it with ForSCAN.

I am going to check the suggestion by airline tech too, he is a wizard and a wellspring of incredibly good information.

yes I did fix my problem.
It was fuse #71.
Not sure why it was blown, but that was the problem.

Does the BCM or TRM show any codes? It appears the FET Protection has shut off the circuit.
