Where to Tap into Horn Wire Ground

[bluestratos]

I am installing a new horn. I have a midwest manual but I cannot locate the exisitng horn or its wiring. I do not want to remove the trunk modual and all I need is to find the negative wire that runs from the horn switch to the horn to trigger my relay.

I have read a "dozen posts including the how to" but no where does it show me this wire or at very least the horns location.


Regards,


Randy

A negative wire doesn't normally run to a switch, just the positive. The ground runs directly from the horn to the frame.

The horn is located on the front left side. when I installed my air horn I used the wires from the old horn to trigger my relay. To see the horn you will need to losen the fog lights on the left side and carefully tilt them away and you can see the horn and its wires. Be careful so you do not damage the fog lights

On the horn the switch controls the negative, I found the wiring block it is pins 5 and 6. 5 is ground all the time, 6 is broken at the switch and returns to the horn to provide a path to ground.



Thanks for the help

Interesting!

Ok, got the horn installed and working per location shown in do it your self projects. It took about 15 minutes to make a custom bracket, 5 minutes to install it and another 15 minutes to actually install and wire the relay. It took about 2 hours to locate the wiring since the lousy midwest manual is in black and white and does not even show a picture where to look for the junction block, lol... It has to be the worst manual I have ever owned. Even the wiring schmatics do not have a legend to clarify the color codes.. I guess that would have used to much ink to print that in the wasted space below the drawing, lol.

Got to say.. wow, that horn wakes up the nieghbour hood now! I used a knock off from my local O'Rielly Auto Parts, it cost $39.00. I wanted to buy the factory model but the catologue listed them as no longer available.

what the make and model is the horn?

Mine is a called a bad boy, sold by O'Rielly Auto Parts up here in Washington.

By the way, after testing the horn and getting everything working I found out that suddenly the horn wire I connected to is back feeding into my accessorie fuse pane. I have it disconnected right now and will need to locate the correct wire closer to the horn I guess. Dang, lol

I think pretty much all horns run the negative side switched. Not sure why but they do. :dontknow:

Hi Lamonster,
You wouldn't happen to know where I can pick up the wiring to the horn easily. When I did the research for the Frunk removal it mentioned the horn disconnect block but it does not show me where it is or what it looks like.

Thanks,

Randy

If it's like the RS it's on the left side under the fog light.

Most vehicles designed in the past 50 years or so are made so the horns are always operational irregardless of the key position.

Horns are switched on the negative side to simplify the wiring of an "always available" horn and, to a certain extent, lessen the chances of a sticking horn.
By providing a hardwired positive to the horn and switch the negative designers could therefore ignore the key position.

That makes sense. :thumbup:

Bluestartos, Try the "green manuals" I found the wiring diagram very easy to read, in colour and it has a legend.

cheers

Thanks for the info. I have the green manual wiring schematic printed out on 24" x 36" paper and I found the horn wiring but, I need to identify where the disconnnect block is (some in the wheel well I believe, and what it looks like. I am guessing it is a two wire plug up in there somewhere but I cannot see it.

Thanks

Louder Horn for RT-S SM5 Spyder

Can anyone direct me to a louder horn for a 2011 Can-am Spyder RT-S SM5. I cannot find that BRP offers a louder horn so I am looking for a louder aftermarket horn. I feel that the factory horn as a safety issue because it is not loud enough for cars and trucks to hear. The Spyder factory muffler is quiet enough that cars and trucks do not notice the Spyder is nearby but I am not interested in going to a loud muffler. I want a louder horn so I can alert other drivers if I need to warn them of my whereabouts in case of an urgent alert. This is the only post regarding this subject since June 2011. Looks like a good horn but I do not want to cause any electronic problems with my Spyder and it looks like this horn or wiring caused back feeding into the accessory fuse panel. Bryan from Texas.

I feel that the factory horn as a safety issue because it is not loud enough for cars and trucks to hear. The Spyder factory muffler is quiet enough that cars and trucks do not notice the Spyder is sharing the road but I am not interested in going to a loud muffler. I only want a louder horn so I can alert other drivers if I need to warn them that I am near in case an urgent horn alert is needed. I have seen only a couple of posts regarding this subject in June 2011. The posts mentioned a good horn but I do not want to cause any electronic problems with my Spyder. This post said that the aftermarket horn wiring caused back feeding into the accessory fuse panel. This is not good and I do not want to void my warranty due to faulty horn wiring causing other electronic issues with the Spyder. Bryan from Texas.
