Re: Stebel Horn Install
*picture may differ from relay used*
No, the switch wires to the button will only power the relay eletromagnet...this current draw will be low, and no problem ( marked 85-86 ).
You will pull the wires off the stock horn and put them there.
You will have to run heavier wire from the battery (fused right near battery) to the horn rely location. I use 2- 12g wires to the front. One (positive) will go to the relay (marked 30 ), then out (marked 87) to the positive terminal of horn. The last terminal of horn goes to negitive (back to battery)
As you can see, there will be a shorter jumper wire from relay(87) to horn.
So you push the horn button, the eletromagnet pulls down the contact which allow power to travel to the horn and out comes a LOUD noise.
Hope this make sense ( and I did it right... don't worry if wrong others will scream) .
You can also run a fused positive single wire from battery if there is a good frame ground near by ( the frame becomes the second wire back to battery)
BTW; I think it takes a 15a fuse as the horn draws about 10amps full on
So do I need to replace the wire going up to the switch as well... I assume the stock horn draws power through the switch as there are only two wires. Not sure where to go from here. Do the two wires from the switch plug directly into the relay, then I run heavier wire from the battery to the relay as well. I am an office guy... no experience with wiring. HELP. My bike is in the garage with tupperware all over the floor.
