1979 Silverado blinker/wiper switch issue

[JROC's Chevy]

Hello guys, I have a issue with my blinker and wiper switch. My truck has the wiper switch in the dash. http://imgur.com/wWPTDkd It also has a wiper function on the blinker in the steering column. http://imgur.com/FnY0xUb It would be number 3 part in diagram which is attached to this part inside the column http://imgur.com/cS4vgxH. The blinker switch looks like this http://imgur.com/4oIX1aq. Ok thats the parts in the truck right now. I went to tear the steering colum down and found: The part connected to part 3 stated above was not plugged into anything. The blinker switch plug at the base of the steering column has 10 connecters(male end) but the(female end) coming from truck wiring harness has 8 connectors which leaves out the green and tan wires seen in picture above. Ok, all I would like to do is have only blinkers on the column and leave the windshield washers in the dash. I have ordered these parts: http://imgur.com/lFtyQE4 & http://imgur.com/lLbFxEa part #1 and it comes minus the green and tan wires. Any help on this would be greatly appreciated!
