1983 gmc 1500 windshield wiper switch?

[militarysniper]

i have an 83 gmc 1500, it is a 4 speed 4x4, i was wandering were the windshield wiper switch would be. because there is no spot on the column for a switch, the only spot would be the turn signal which is there, someone switched this truck over to a 4 speed and they used a different column
no i am talking about the switch that most of the time is on the steering column
