Is there a relay missing?

[vtchequers]

Shouldn't the brown socket have a relay on it?
This is a 2000 W reg Zafira, pre 03 facelift.

Maybe...?
it could be for an optional extra your car doesn't have, or possibly something that's required for a foreign market.
Is anything not working on your car?

Your owner's manual or a label on the fusebox cover should tell you what it is for.

Probably something your car doesn’t have, heated seats or someht8ng. Does everything work?

Sleep a little now

The strange thing is that the answer given in the above topic was from someone mentioning an Astra, found that really funny

Perhaps you could laugh yourself to sleep
