'94 IM headlight wiring

Did you look at the CMC wiring diagram in the build manual.  I believe it relies on the headlight switch and dimmer switch to control headlight - stock it has no relays for headlights.  

When you flip the dimmer switch, do your high beams go off or stay on?

I'm confused (not an uncommon event).  The topic line says "'94 IM" but the post signature says "'58 CMC".  That will almost certainly affect the solution.

Were you aware that in certain lighting conditions hash browns with a little ketchup can look like shrimp?

Looks like in Smooth's profile he has one of each listed (CMC and IM).  Even the dune buggy harness is devoid of relays for head lights.  The 50-65w draw has to put some arc/heat on cheap headlight switch contacts hence the need for relays on fog lights and head lights.  If your headlight switch gets warm to touch with lights on consider using relays.

If it's a '94 IM I would be willing to bet that it has relays.
