That component is most likely a resistor used to suppress voltage spikes
when relay is switched off; that spike can cause switch contacts to wear
prematurely and can possibly head back to ECU or other sensitive component
and harm it.

Some pics of relays I opened up. Yes. I have too much time on my hands.   ;)
