This is what makes this such a cool forum. I even convince myself I know everything. Then I find out I know nothing at all. I wonder what the switch is like for the newer trucks. I don't know what year they changed. You must be able to pull out the switch in park and headlight positions. If I had a decent dealer close to me I think I would have the parts dept. let me look at them to see if they would interchange. Anybody out there that has better knowledge, Please jump in here. Bill
