Question
Where does the dimmer actuator go in the steering column?

Answer

dimmer actuator-www.st   Hello Elizabeth.
I can only assume you are asking about a GM steering column with tilt.  If so, here is a picture of where that part fits in the column.
I hope this is what you wanted to know, otherwise re-post your question with a bit more detail so I might know what you are working on.
