My cluster, missing a relay?

[charger9]

I need help with the back of my cluster for my 68 charger.
I have seen pics of other cluster and see there is a small part right under the circuit board.
It looks like a relay and is fasten by one screw and it looks like a wire go from it and into the
dash limiter. Is this correct and what is that "relay"? What function does it have?  It is missing on my cluster.
Hope somebody can help me.

If the part is a round metal canister it is a condensor to suppress electrical noise.

Yes thats the one I meant. So maybe it is not so importent to have one if I dont use my radio?
Maybe you or someone else also can help me to locate the ignition light relay?

as stated, noise supressor.

Time delay Relay/Flasher... maybe Mopar dealers still have them Since 90s cars also used them. PN 2889565... mostly sure has a supersedes number

I think Napa has them
