The relay is labeled "Turn Signal Relay" on the top. The relay has four terminals:
* C (Control): This terminal is connected to the turn signal switch.
* L (Left): This terminal is connected to the left turn signal bulb.
* R (Right): This terminal is connected to the right turn signal bulb.
* B (Battery): This terminal is connected to the battery.
The relay works by switching power from the battery to the left or right turn signal bulb, depending on which turn signal is activated. The relay also causes the turn signal bulbs to flash.
