Stuck in Requiem, Level 10 (Closure)

[Sha]

Hello there
I am stuck at the part where you have to use circuit boards on a distributor according to a diagram.
I've been on it for a while now and I really can't think of anything that makes sense. I don't know what to do.
Could someone give me a hint? No spoiler please.

Thanks

Nvm, Got it.

Just an help, no spoiler, remove all card you inserted on the circuit closet, and use only one, check the light, if you played penumbra Black Plague, it's the same puzzle than the bloody dream on the realm with the barrels and colored circled fires.

good luck
