If you had a standard column you probably had the fiber optic light to the gear indicator.It's next to the speedometer. The tilts had a regular wired light with the bulb in the column behind the indicator.
The wire can be connected to any of the cluster light wires or there may be a bulb that goes in place of the fiber optic light that the wire can connect to.

There may also be a spade next to the pnl lts fuse in the fuse panel, that you can plug the wire into.
