Removing the passenger side horn

The horn is held on by one 1/2 inch head bolt. There is also one wire that is pushed onto a tab on the horn. 

The retaining nut on the back side was rather rusty and started spinning in place. Fortunately I bought some Vise Grips this week. 

With the Vise Grips holding the nut the bolt came off just fine.

This is a picture from inside the car just for fun.
