91 blazer turn signal help please.

we are reassembling a tilt steering column on a 91 blazer. we are stuck with a part that is a small arm, with a hole on one end and a small rod on the other end, thinking it has to do with the dimmer switch, turn signals and silver rod coming up from steering column. i need full details on how to re hook-up anything and everything that has to do with the turn signal. if anyone has any suggestions or answers, diagrams really help too. and if anyone has the number descriptions for each piece on the diagrams that would help too. you can e-mail diagrams to [email protected]

thanx,
J Mix
