Was looking at the horns today on the 83 300D. I noticed they have two wires going to them. I'm used to horns only having one wire going to them. What are the two wires for on my 83. I assume one is for the 12V signal to blow the horn, and the other is ground? Correct, or???

Reason I ask is if I ever want/need to replace them.

Thanks,

Glenn
