It makes a difference on whether you have sealed beam or aero style headlights on the fuse numbering.
High beam indicator for both sealed beam and aero headlights are on the same side of the fuse as the headlights. It could be that the grounds are messed up. You need a ground to complete the circuits.
For aero headlights, power comes from fuse #10 (30A) in the Battery Junction Box (under hood), thru the headlight switch, to fuse #16 (15A) in the Central Junction Box (under dash), feeding both the indicator and the headlights. Low beams come off the headlight switch thru fuse #9 (10A) to the left headlight and fuse #11 (10A) to the right headlight. There is a ground for both high and lowe on each side, and a separate ground for the indicator.
If you have sealed beams, the fuse number feeding the headlight switch is #13 instead of #10.
