INST Fuse blowing

Most likely in the orange wires, here is how this works:

The dash dimmer actually GETS power from the tail light / park circuit fuse, so that circuit must work "first"

That power goes through the dimmer, "out" on the tan, and TO the instrument fuse via the tan wire, then out to all dimmer controlled lighting on the orange.

Since there are quite a few, you hope for "luck." Since you meddled with the cluster, I'd start there. Perhaps you have a lamp or socket screwed up in the cluster, or pinched something in the harness getting it back in

If you have a column shifter quadrant I'd check that, the ashtray if equipped, and from there ??

What else did you move/ work on?
