What Are These Relays/Switches on the Underdash Harness?

Not sure what the first one is; 2nd looks like the time delay relay and the last one is either your turn signal or 4 way flasher

Time delay relay for what? The 4-way flasher makes sense given where it is located on the dash. I will see if I can track down the schematic. The first one is really stumping me. Hope for some more feedback. Thanks.
