Here's a very simple Schematic, it's correct except for a Stebel Nautilus, the fuse should be 20A.

Any computer wizards out there who can change this to reflect this and possibly the power wires and horn chassis ground to show 12G ?

Here's another dual horn set up, and once again,and since it's showing a 10A fuse, I believe it's for two electric horns like Magnum blasters, of course you would need a larger fuse for dual Stebels,man that would be cool!! and in this case their taking the horns ground all the way back to the battery, I just go to a good chassis ground.

And a couple of my favorite relay schematics, if your relay only has four pins, pretend pin 87a is not there, doesn't matter, you can use a four or five pin relay, you wont use pin 87a

I am not sure how you are going to the the relay to work by hooking a switch with no power up to it??

One or either 85 or 86 goes to ground and the other gets power from the existing horn switch. Your diagrams shows the switch hooked up as a loop, which would do nothing.

If you are trying to show what to do with the existing wires, it will work, but the drawing is not accurate.

Well it's a cartoon type schematic, it is not a total schematic of the bikes electrical system, but yes you are correct about the horn button not showing the extra wires providing the power and ground, I think most people will understand that the horn button is powered, when pushed , power will be supplied to the relay from the horn button contacts, go through the coil, return through the horn button and then be grounded by one of the wires not shown in the schematic, I'm surprised you didn't say the hole bike would be dead since the battery in the first schematic is not grounded? Heck the second schematic doesn't even show the horn button, how can this one work without a horn button to push???? But as you mentioned, of course it's showing you what to do with the existing wires, the two wires that are removed from the existing horn, will be hooked up to the relay pins 85 & 86 just as shown in the schematic, so now instead of supplying power to operate the horn , they will now supply power to energize the coil in the relay, so it is accurate, just not complete , the wires shown are the ones you need to work with, for our sake, we'll assume every ones bike out there is going to have a ground for their battery, and the horn switch is already powered and has a ground , and there will be a horn button.

And I am pretty sure every one who sees this, well I guess almost every one, will know it is showing you what to do with the existing wires, and what you need to add. and if you hook your existing horn wires up to the new horn relay, just as shown, you are wrong, it will go BEEP BEEP!!

I just installed my Stebel and I am an electrical moron! I ordered the Easternbeaver single horn wiring kit and it was a simple plug n' play. I consider the wiring kit money well spent ($40 bucks w/shipping) not to mention the time it saved me.

Yes I would agree, if you don't do allot of electrical work, it does make it easier to use a pre fab harness, it's nice they are available' but it's really simple to wire it your self, if you can strip a wire, crimp or solder a terminal , probably crimp is the easiest , any one can do it, and it's actually kind of fun.

Just thought I'd post the pics to help any do it your selfers .
