No tail lights
 

I have apparently no running lights/side marker lights and no tail lights. I do have instrument cluster lights and my illumination fuse is intact. Any thoughts? Reading around some people think it's the headlight switch itself.

Solution: Harness to illumination switch needed some finagling

When all else fails just shake the wires harder!

Glad you figured it out!

Be careful I had 7 that melted those harnesses and and switches like no body's business. Never could find the short. Used to be fun to see smoke come out the cluster and that wonderful smell of magic smoke.

I had the same issue on my FD. It was the front harness that had shorted out causing the cluster headlight switch to melt every time. :(
