trailer hitch wiring harness troubleshooting
I've purchased a cover and cargo net to protect my mountain bikes while transporting them on my rear rack. Then I realized my tail lights would be hidden, so I bought a kit to add lights, and next discovered the pre-existing trailer brake-light extension plug is not working.
I've never pulled a trailer or tried plugging in auxiliary tail lights on my 2001 E250 before, so I just discovered this now. I'm not confident that resolving this is within my skillset, but willing to try. How do I proceed to diagnose and repair this issue?
