Horn Location on 98 2.2

Hi. I heard a horn honking earlier tonight, and figured it was just the neighbors messin around. But it wouldn't stop. After about a minute I went outside to find it was MY truck. I couldn't get it to stop, so I pulled the fuse. I washed it twice earlier [basic first time, didn't get clean so station gave me a free Ultimate..underbody as well], and I'm thinking maybe some water got up in the electrical and messed something up. Where is the horn's location? I looked but couldn't find it...but it was also dark. Any help is appreciated [ANY, ANY AT ALL, seein as how my other posts go unanswered]

Bah. It was the relay, not the fuse. Sorry for any confusion.
Today I tried putting the relay back in and everything was just normal. I went down and got a new relay just to be safe though. Hope it works out
