I have a 98 4runner in which I recently installed a trailer hitch converter kit to get lights working on a jetski trailer. Everything was working fine for a bit then last night I noticed when it got dark that both my tail lights on my 4 runner and on the trailer dont work. The gauge lights on the dashboard that the dimmer switch usually controls also no longer work. I assume that there is a short somewhere or a fuse has blown...but there really are not that many fuses that I could see and all of them looked fine. I guess I should replace some of them anyway just to test it. Does anyone have any idea what else it could be...or for that matter what fuse is associated with these.
