Hello!

My horn is not working.

Can You please tell me, were there originally two horns on my 88' Sierra 2.0EFI 3-dr hatch or only one? Now I am having one horn on nearside of the car's engine bay.

There are two wires connected to the horn: yellow/silver "-" and red/black "+"

The problem is that yellow/silver wire at one end is connected to horn BUT at the other end it is cut off and hanging in the air. I cannot see any other cut off wire that could be the continued yellow/silver one. Can someone please tell me where this wire should be attached?
The black/red one is ok.

Thanks!
