They "control" the operation of the battery gauge. They contain 4 amp fuses.

I can't remember off the top of my head where they connect. No they won't affect the operation of the starting circuit or headlights....

The one on the passenger side connects to the junction block closest to the battery. The one on the drivers side connects to the main “splice junction” in the wiring harness behind the headlight.
