Step 2. Modify and Install Wiring

I was reluctant to make my own wiring harness because I’d never done such work before. However, I declined to buy a ready-made harness because I wanted to maximize my freedom to adapt and customize the wiring as I saw fit. The pre-made harnesses also cost quite a bit for my budget, and I’d read that certain harnesses didn’t fit some installations as well as expected.

Using a relay is reportedly essential because of the high current draw from the horn’s compressor. The same applies to using 12 gauge wire where appropriate and a properly sized inline fuse.

At every wire connection, I applied heat shrink tubing to protect the wire strands from eventual work hardening and breakage. To delay corrosion, I also dabbed anti-oxidation grease into and over the exposed wire ends inside their connectors.

At the front end, the connections of the existing horn wires to the new wires were easily protected from the elements by adhering them to the underside of the plastic radiator hood using double-sided tape.

The wires ran easily from the front end back to the battery compartment, and I mounted the relay to the battery’s retainer strap by simply girth hitching a heavy elastic band around both items.

A Thank you

Dear Mr. Happypants,
I just wanted to thank you for all the detailed instructions on installing the horn. Your diagram and pictures helped me tremendously and I would not have been able to do it without your post.
Where did you get the bracket to attach to the frame?
I am planning on going up further on the frame so that the horn is facing forward and I will have to figure out a way to attach it. I know it fits higher up and I may just use wire ties but I am working on another solutiuon.
Thanks again!
Jeff

Bracket

Hi Jeff,

Thanks for your note. I'm glad you found the tutorial helpful.

I made the angle bracket from some 1/8" thick aluminum flat bar stock from a local hardware store. It's easy to bend (using just pliers) and drill holes into (using a hand-held power drill), but strong enough to hold the horn rigidly in place once it's installed. I also found that using such material allowed me to easily customize the bend shape and the hole placements to my personal preference, rather than trying to accommodate the pre-drilled holes in a ready-made steel angle bracket that I tried on for size earlier in the process.

I hope that helps. All the best Jeff, and may you never have to use your horn in anger!

Mr. H

other bracket

Hey Jeff,

It just occurred to me that your question may have been about the other part of the attachment mechanism, which is a "grounding clamp" that you can find in pretty much any hardware store.

Cheers,

H
