I got the Howard's Horns this week and finally got around to installing them last night.. I had to drill out the hole on the cowbell hanger because the bolts that came with the horn were too big. Then, I had to rummage through my parts bin to find a 5/16 nut because they shorted me one. And now I can't figure out how to run the wiring. They give you a rough schematic and some vague instructions for wiring, and then recommend you have the wiring done by a "certified mechanic". Sounds like liability wiggle to me. So, bottom line, my question is......Can anyone please walk me through the wiring of the relay for the horn on an Ultra Classic? Thanks for any help.

 

Just try different combinations until it stops blowing fuses. Sheesh.

 

Print the schmatic they sent, and Ill try to help! l.ray

Thanks

 

1)connect #85 on the relay to the negative side of the compressor, then connect the negative side of the compressor to the negative post on the battery, Or to the negative from your old horn.
2)Connect #30 on the relay to the positive side of the battery.
3)Connect #87 on the relay to the positive on the compressor.
4)Connect #86 to your positive from your old horn.

 

So I'm making two connections from the same negative post on the compressor? Am I understanding that right?

 

Sorry it took me so long to get back to you, but according the diagram you posted yes two connections to the negative post on the compressor.
