Not going to be the issue here, no trailer wiring or other errant hookups. I unhooked the dimmer switch, replaced the fuse 2, and all my nighttime exterior driving lights work fine. Dimmer switch checks out fine. I shorted the pigtail to the dimmer (basically 0 resistance = full brightness condition) and fuse blew instantly again. Something related to the dash lights is the culprit.
