Help needed #5 5A Fuse location

Working on a 1974 Challenger here.

Wondering if anyone ever came across this?

On the fuse holder, the #5 Fuse, tested with a test light, has NO power on either side of the fuse.

All other fuse's and terminals tested out just fine.

I need to start here as this fuse controls the Dash lights.

Your help would be appreciated.

Thanks
