I just bought some Hella Dual Trumpet horns and need to wire them up on my 99 GS. Has anyone done this install? I'm not sure on how to wire them. I really don't know too much about wiring in general to be honest and the instructions aren't that clear. Any help would be greatly appreciated.

 

Naw. I've never done any work with, like, tricked out horns, but I think the important thing would be to make sure they get the right voltage.
Other than that the mounting might be a little time consuming. Sorry I can't help much more than that though.

 

Establish a good ground first. The red wire most likely has a fuse on it, take it out to kill the current. There may be one more wire in most cases, I'm not sure how many yours came with, but that is most likely for the switch. That will be the wire that allows you to depress a button and get noise as opposed to a constant noise from just having a hot wire present. Hope this helps.
