What goes here?

This is the drivers side inner fender and upper fender and I was wondering if anyone knew what was originally located in these holes. I'm trying to put this truck back together after it was stripped out for painting and I don't know where half of the items go. If anyone has pictures of an original engine compartment would be great. I could see where stuff was mounted and how the wires were routed and stuff like horns and whatever. I bought the chassis manual but it doesn't show all the stuff I needed.
