where is the fuse and the relay for the horn

If you go to the link below and scroll down to where you see PDC in red. Below it you should see two photos. Both show the location of the horn but I prefer the one on the right since it is more of a photo of what the relay looks like. That is for the WJ http://wjjeeps.com/fuses.htm If you have an XJ then go to the link below and scroll down and look for the horn. I don't know enough to know if you have the xj or wj. I hope this helps. http://www.lunghd.com/Tech_Articles/Electrical/1997_UP_Fuse_Identification.htm
