I recently picked up a tilt steering column out of a '71 chevelle 4 dr. I put the column in my '70 chevelle SS and I noticed that the switch(not the key switch) is different and that the connectors will not work on the tilt switch. Has anyone done this conversion and do I need to get the other wiring harness off of the 4dr? I would hate to do that, cuz the 4dr has air and my car doesn't, so I would have a bunch of extra wiring (messy). I tried changing the switch off my original column and putting it on the tilt, but then the ignition key works backwards and I doubt it will start the engine? Need Help!
