battery dying

[67Fleet]

I've got a draw on my battery and it's coming from the horn switch. When I took my steering wheel off the last time I somehow lost the part that insulates the switch so it doesn't have constant contact. Is there a fuse on the panel that operates "just" the horn? My fuse panel has overspray on it and I can't read the labels. I've got to order a new horn switch setup from LMC so I have a permanent fix, but wanted something temporary to get me by without draining the batt. I've unplugged the horn but it still draws current.
