Wrangler Headlights - Please Help!!!

I have a 98 wrangler and the headlights stopped working.

I ohmed out every single fuse I could find behind the glovebox and in the main distribution center under the hood - all ok. I replaced the headlight switch. I applied voltage to both headlights with a battery charger just to verify that they were not burned out - they worked fine.

I could not find a single fuse labled "headlight", "Hi beams", "Lo beams", etc., etc.

Can someone tell me if there is some hidden relay or fusable link that lurks somewhere on this vehicle that would cause the lights to fail?!?!

This is driving me nuts! I would like to get a wiring diagram too if anyone knows where I can find one online. Last resort is changing out the dimmer switch...but doesn't there have to be a headlight fuse somewhere...???

Any help is appreciated - Scott
