2000 Toyota pre-runner passenger side brake light not working.Dog chewed hitch wires up. Have spliced all colors back together but light won't work(brake only) tail and blinker work! Anybody have any wiring diagram for this . I could just straight wire and bypass the plug for my hitch plug? And yes I tried new bulbs.

Here you go.

Looks like you could hook to the right side tail light.
