I'm working on a 1971 F100 that will be my shop truck when I'm finished. No work has been done on the truck for many years so I'm going thru everything. Can anyone tell me what the small box under the dash with two vacuum lines going to it does? There are two wires coming out and going into the under dash harness......never seen anything like it.
I work on mostly pre-war stuff so this will be interesting.
