turns signal switch?

Why are you pulling it out? Are you replacing part or all of the switch, wires, or what? If you can get the wires to pop out of the harness, your idea will work. I've done it that way, and I've also cut the wires (leaving enough room on the harness end to splice the wires back together). Either way, tape a string to the end of the wires before you pull them through the column. That makes it a lot easier to pull it back through and downm to the switch.
