1977 CJ7 Fuse Box diagram

I am trying to get a picture or physical layout for what each of the fuses in the fuse box are for. Specifically, I am trying to determine which one of the fuses are for the Horn. I have good wires from the horn to the steering wheel. I have purchased a new horn relay and new horn, but I can not determine why it will not work. I assume it most be the fuse, but I can not determine which one of the slots should be for the horn.

Search this forum for a thread titled "basic wiring 101, getting you started" by jeephammer. It has links to wiring diagrams for cjs by year. It has alot of great info. I downloaded and printed the diagrams so I could use them in the shop.

I dont know how to post a link to that thread, maybe someone will come along and do it.
If you use the search this forum link you will find it pretty easy.
