tail light circuit short

Ok, so from the beginning. I broke the ground wire for hte light in my boost gauge awhile back. Fixed it yesterday, but hadn't insulated the wires at the boost gauge, and it shorted out when I tried it. I insulated the wires, replaced the tail light fuse, it blew the new fuse when I tried again. So now I have no dash lights and no tail lights.

So do I have another short somewhere? Or did something else get screwed up when I shorted it the first time?

Edit: fixed it, ran a new power wire from the boost gauge to the rheostat, old wire was shorting out somewhere in the a-pillar.
