Since you can't really stick your head under there while driving, you could try the poor man's stethoscope trick.

Get a piece of flexible hose long enough to reach from those relays to your ear. Tape one end to one of the relays. Hold the other end up to your ear while driving and listen for the clicking. Stop and move the hose to the next relay until you find the one making noise. If it's not one of the relays, mount the hose in various places under the dash until you track it down.

This is how you isolate sounds in an engine bay without touching anything with a mechanic's stethoscope. It won't give you the sound inside the engine, but it's great for tracking down exterior sounds like a squeaking pulley that you don't want to stick a probe into while it's moving.
