We were discussing this swap on another site last week. Someone put a Cordoba tilt column in a Challenger. He said the wiring is a direct swap. The columns were sourced from Saginaw and are wired for a GM. When they were used in Mopars, there was a conversion harness in between the column wiring and the dash wiring. As long as you have that conversion harness, the wiring is a direct swap. For installation in a Challenger, the factory rag joint needs to be cut off the column and the Challenger coupler/shaft welded on. I know things changed in 73 on the B-bodies. Do they use the old coupler or a rag joint like the Cordoba?
