The key in the column on a tilt pulls a rod that connects to the switch under the dash that is attached to the column with two screws.

Do you need the lock & rod assembly? Or the switch attached to the column under the dash? Or the wiring connector(s)? ( Older harnesses had 1 connector, newer there are 2 connections that plug into the switch). Both connectors (one piece or two piece) are part of the dash harness. Gene
