Installing an air horn, wiring question.

[drew2bm]

I am installing an air horn on my 95 RS, and I needed to know which wire(color) is power and which is ground out of the two that go to the horn itself.
Also, is the horn ground activated or power activated?

no idea, ill be doing this mod prob morrow, but take a test light, and then see if theres a constant to the horn, or disconnect the ground, and connect test light and have someone push on horn and see if theres power thru them and that should help, be sure your horn wont collect water inside of it and will drain out.

DSMs switch the ground on most everything. That is, they switch the _relay_ ground. You should be good-to-go hooking the compressor straight up to the power lead to the factory horn out at the fender.

And yeah, aim the horns a bit downward, and keep them away from the tire spray.

Did you get FIAMMs or Stoebel?

I got the FIAMM's. So which color(s) is the the ground wire on the horn connection harness?
