Instrument cluster questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just pulled this cluster. Anyone happen to know what this hole marked with a "?" in the cluster is for? It had nothing going to it, and I believe the same applies to my other truck. Perhaps it just takes a bulb and socket like most of the others? The manual says it's an Instrument Cluster Light.

The manual also says the hole (marked "OK") is an Instrument Cluster Light. But this takes a socket fed by a black wire, which appears to come from the turn switch.

Thank you

theyre both just lights need those black holders the others have

I didn't see that one marked to cluster that's the one for the prndl light should go in one of the missing bulb sockets there probably near the spedo

firedemon is correct....

The one marked "Cluster" is the fiber optic for the gear indicator on the column. It goes in the hole by the speedo marked "OK" The other one just takes a regular bulb & black socket.
