I sent some pics to Dennis Yoo from a spare tilt column I have. I pulled the column out of a 1969 Mach1 in 1980. Put a new service switch from Ford in it. Ran the column in a 69 Mach1 for 4 years and then my Shelby until 1996. everything worked. Pics are how I wired it and the "spare" wires from a 1 switch fits all service part. I hope this helps some others in the future.
