There is a small relay box next to the under hood relay box(left corner)
There are 3 relays inside that box.What are they for?Thanks

 

FYI: When referencing anything on an automobile it's always reference from the driver's seat if not noted. i.e. The part at the right rear corner area under the hood is call ABS Relay Box.

Names of the relays in that box are:

ABS Pump Motor relay (big relay)
ABS Fail-Safe relay
TCS relay

There's also a relay box which also have 3 relays in it on the left side of the engine bay call Mufti-Relay Box.

Names of those are:

Shift Lock relay
Seat Heater relay-99; Seat Lock relay-00-01 (same location)
Security Horn relay-99; Tail Lights relay-00-01 (same location)

 

Actually from the Drivers seat, it would be the "Left" rear corner area under the hood. Right rear corner area under the hood would be passenger side (and a completely different fuse/relay box
