Dimmer Switch and Cruise Control Connection

[elmono]

I'm replacing my dimmer switch and I'd like to know if I need to remove anything to do so. It looks like I'll need to lower my steering column to reach the bolts, but is there anything that I need to watch out for? Also, I'm replacing the turn signal lever and I don't know how to run the cruise control wire down the column, nor do I know where to plug the connector in (the previous owner simply cut the wires at the lever, so I have nothing to follow). What do I need to remove in order to do this? Thanks, Chad.
