in the feb. issue of rod&custom magazine, there is an article on how to make the turnsignals work with a toggle switch. american autowire was the outfit that made this kit. the article had a diagram that showed a gm turnsignal harness used,and the routing of those wires thru a relay and toggle switch. i think if a guy just thought thru the different color schematics of any column, you could easily do the same using your existing column. there is a slight mod to do to the existing wiring so the back feed problem is eliminated.
