I just completed installing my Supertones using your 'instructions', but with a couple of tweaks:
1. I used 14/16 guage speaker wire for the power lead and ground lead, whereby I twisted the +/- ends to connect to the female connectors to the relay, and I was able to ground the horns together. This way I didn't have to use vampire clips. 2. I used dielectric grease and heat-shrinked all my connections - I'm a neatness freak. 3. I installed the horns on the hood latch release area.

Excellent write-up!
Based on what has been said, not only do the horns look good, but that they are producing a louder tone - which is what you want. What I don't understand is since the Supertones are supplanting the stock horns, then why is there the need for the secondary relay? Is there a substantial difference in amperes [draw] between the Supertones and the stock horns? If there is, then I see the need for the relay. I know that outside of the US laws, rules, requirements and availability of equipment and parts can and has varied and thus when one purchased such a kit, whether for primary or secondary installation purposes, one got a complete kit. Just curious; and thanks. |

The reason for the relay is because the OEM horn wires are pretty wimpy which can potentially prevent the horns from drawing enough current to be their loudest. With the relay, you use the OEM wires to trigger the relay then wire up the horns so they have essentially a direct connection to the battery with some adequate wires.

Thanks a lot for this write up,
Just installed mine today. The only thing I did different was that I went with two vampire clips into the ground wire (3 connection for the relay and each horn) |

What do you do with each wire that runs to each factory horn? 1 factory horn lead attaches to the hella relay. Where does the other factory horn lead go?? |

You can let the other horn wire just dangle or leave the OEM horn plugged in and in place.
Or do what i did: |

Excellent write up. I used this write up, along with placing the horns on the hood latch bolts, and the wiring diagram in the middle of this post here:
http://forums.nasioc.com/forums/show...=510523&page=5 to perfection! I also used heat shrink tubing, and anti-oxidation grease (similar to dielectric grease I believe), and wire loom to cover it all up. |

I picked up the "made in india" kit (the 300/380Hz combo) then added the 500Hz horn later. The little tab in front of the radiator is a nice mounting spot. I was able to pick up the single horn from www.rallylights.com. |

I've got mine on order and I'm no electromotrician, but I'll give it a shot
**looks up the word "relay" in the dictionary** I've got calibrated noise dosimeters at work, I'll measure them and post when I get them installed - and see how close to 118 they really are! - with appropriate hearing protection of course. |

Supertone noise measurements
OK, if anyone is still reading this thread, I installed a 300/500 MHz set of Made in Germany Supertones behind the grill of my rex.
I measured the noise today using a calibrated noise dosimeter. The results are as follows: Within 2 inches of the horn: 135 to 141 dbA Six feet away at knee height: 118 dbA Six feet away at head height: 110 dbA Hearing protection is recommended in any workplace above 85 dbA and required above 90 dbA average over 8 hours. I think every 3 decibels the sound pressure energy doubles. The remaining interpretation I'll leave to you. Just a little industrial hygiene for y'all. |

I just installed mine today. I followed the write-up in this post. The only thing I did differently was plug the wire from the factory horn directly into the relay. I thought it would be a little cleaner that way. Well the horns dont work right now. I was wondering if that was the cause. Any help would be great!

I'd simply trace each wire to make sure it's all hooked up correctly. I'm going to assume you either have a bad ground or something not connected correctly. |

I also bought solid copper wire for some reason so I don't know if that would matter. For my grounds I did them in the same place as you did. When I took off the bolt the little washer fell and I lost it, could that matter? I am just throwing ideas out there. Thanks for the quick reply

Did you sand/file off the paint so your ground hits bare metal?

No I just took out the bolt and put the horn wire and the other one back and tightend it up. Do you think that is the cause??
