Horn Question

Share this page

The relay will have numbers on it

86 and 85 will be for the horn and 87 and 30 for the switch. You can run the brown/green (hot) to 86 and 87 and the brown/black (ground) to 30. You would then run a line from 85 to the horns and then brown/black (ground) from the horn.

OR you can run brown/green to 87 and a separate hot wire (directly from battery or solenoid) to 86 but still brown/black (ground) to 30 and wire from 85 to horns.

you can see it here

BTW since they are all just switches, there is no polarity issues so as long as you get the pairs right, you are good to go.
 
Perfect, thanks. I'll pick the horn up today and try wiring it in tonight.
 
To answer your question Bugedd, the original circuit will just power the relay so you horn button supplies the ground to actuate the relay. The new wire will send power straight to the relay which will then pass it on to the horn. The horn will then have to supply its own ground. Hope this helps.
 
The one new wire that I ran is a #10 direct (well inline fused) to the relay to provide power to the STEBEL (air) horn. I grounded the horn with the same bolt with which I mounted it to the car. Those things draw 18 amps!
 
Okay, wired it up and see if I can get some help. I hear the relay working, but no honky. To 30 we have constant hot to the battery, 86 is the brown/green hot wire for the horn (stock wire), 85 is the brown/black stock wire, and 87 feeds the horns.
The horns have 11 and 44 on them, from what I can tell in the poor schematic 11 is hot. I have the grounds from 44 going to the mounting bolt for the horn on the sheetmetal.
Thoughts?
And I just tried switching wires on the horns and trying a new ground, nothing. And when the horn is pushed, I am getting 11v at the wires feeding the horns.
 
Okay, I got it working. I won't say what I did wrong, because there are time when one doesn't admit to such bonehead things. But it was one of those where I question whether or not I should possess tools.
The 110db Hella horn is hella loud. I made my girlfriend jump as she was making dinner, and she burned herself. Oops.

been there, done that :wall: :devilgrin:

but you have to tell (Jedi Mind trick)
 
darn mind tricks......
I ran the hot wire to the battery, put a connector on it, loosened the battery clamp, and then got distracted by other things and never did actually connect it to the battery. Duh.
 
:lol: Been there - done that!
 
Well, we have all done things like that but it's great to hear someone admit it!! Chuckle...
