Wiring for factory fog light switch on 87 4kq

[Mholme3 at aol.com]

I'm sure it's been covered but I can't seem to find a post in the archives.  I let a friend borrow my Bentley so I don't have a clue where to begin.  I found a factory fog light switch in a junkyard and I wanted to use it to control the H1 driving lights on my euro lenses.  I want to keep it as clean as I can using the factory fog light fuse and relay location. Can anyone tell me if all 4ks are wired for fogs?  Also,  I need to know what the terminals on the back of the switch go to.  I  know the H1's are high beams so I would have to change the switched power source going to the relay.  Thanks for any help.
