I repaced my ignition switch

I repaced my ignition switch. When I removed the old unit the wires slipped out of harness. This would be the harness the igntion itself plugs into. It is a round plastic wire holder. It is marked 15x, 15t, 30, and so forth. There are 7 wires that go into this harness. This is an early 1989 model that does not have the locking tranny switch. Please help as we are going into freezing weather and this vehicle is in danger of freezing without winterization.

Roy,
Would you happen to have the color of wire that goes in the slots? I.E. 15x=red wire?

I hate to be a pain but the diagram I can't seem to enlarge to view. The color codes would be of great help.

Roy,
Thank you for your time. I have enlarge the diagram but once enlarged it becomes too blurry to read. I was hoping for the color codes. I will continue to attempt to find what all the codes corresponding to wire colors are. Thank you again.
