I am having some trouble locating a post on the wiring for the ignition. I am having trouble with my truck (but whats new)

Anyway Maybe someone can help me. I recently put another starter in my truck and she was starting fine for a few days and then about a week ago I tried to start it and I truned it all the way to start position and nothing but when I went to let it back in run position it cranked so I was fiddling with it and it would only start by turning all the way to start and then an 1/8 of a turn back to run for it to crank. Well now She doesnt even do that anymore. She doesnt do anything

And frankly I am getting tired of pushing her or parking on an incline to bump start her. So I thought I would go to the store tomorrow and get her another ignition switch. (also the truck was stolen before I got her) so the ignition was busted and basically starts with any flat tip screwdriver.

Well if anyone can remember the post I would greatly appreciate it. Or if someone has any suggestions let me know.
