I need help, I am trying to replace the key switch in my truck and can not figure out how to remove the old one..It is an automatic and does not have tilt wheel.. Can someone give me some pointers!!!

 

Chilton's manual part # 8166 has detailed instructions with pictures. I am a fairly experienced mechanic but I would not do this with just an explanation without pictures. You should be able to get the information you need at the public library if you don't want to buy a manual.
