2000 Toyota 4 Runner Trailer Lights Not Working. See your dealer or rental agency for the correct type of wiring and relays for your trail- er. We tested it and it is the truck, not the trailer.
Running lights work on trailer when hooked in, but brake and blinkers do not. Click here for FREE programming instructions from NorthCoast! Right side is okay new bulbs.
The batteries were good (I checked them with a volt-ohm meter).

The trailer lights work just not the running lights. OTOH, I have wondered why the silly city engineers. Runs perfectly, but does need some.
