wiring
 

I'm currently troubleshooting a problem with my taillights. My driver's side lights turn on normally, but my passenger side lights do not. The Chilton wiring diagrams are of no help at all. Both taillights share the same fuse, and I've checked the filaments of the both bulbs and they are both fine. This doesn't seem like it would be such a rare problem, so if anybody's dealt with finding bad tailight grounds or something close to this, I'd really appreciate the advice :D
thanks,
