Is there a separate relay for the main headlamps and a separate relay for the high beams? Also, is there a separate fuse for each of these headlamps?

There is not. I attached the wiring diagram and the close view with the low and high beams highlighted. The high beams are run off the fog relay and there is a separate fuse for the left and right headlamps.

Let me know if there is anything else you need. Thanks

It is in the underhood fuse box. I attached the information for this fuse box.
