Hi, I'm attempting to replace my 93 Civic DX single horn w/Caddy 4 note horns set but am having difficulties & would appreciate assistance.

I have the 4 horns bolted onto the frame & have them connected to a 12v relay as follows:

30-positive fused to battery.
85 negative terminal.
87 connected to the 4 horns via a harness.
86 connected to BLU/RED wire that was previously connected to the stock horn.

Unfortunately, when I hit the horn button nothing happens. Any suggestions?

Thanks.

 

did you check to see what signal comes out of the blu/red, do you hear the relay click over wen the horn button is activated.

 

Are you trying to run all four horns off the same single relay?

 

I am the mother ******* man. Just saying. Here.



In return I want a QUALITY vid of the sound when you're done.

 

yes off a single 40A 12v relay. I believe the 4 horns draw 22A. Do you think I need 2 separate circuits & 2 relays?

 

Caddy 4 note horn?

 

See above.

 

I would say yes, you need 2 relays.

 

This one?


Can we find these horns on other vehicles?

 

I'll let you know, I started researching as soon as I posted the wiring diagram LOL. I'm interested!

 

The horns are easy to locate either at local junkyard, I pulled 2 sets off early 90s vintage Caddy's, or you can buy a set of 4 for $80 via Ebay. There are even videos on how to repair/recondition a nonworking unit.

Thanks for the wiring diagram. However I had previously come across it. The 2 relays seemed like overkill but perhaps that's the issue. I checked the horns on a 12v battery after purchasing them. I just cant seem to get them working on my Civic, yet...

 

I've found 3 write ups with them SUCESSFULLY installed in a Honda (2 civics and 1 Accord) and all 3 used 2 relays. Hopefully that will solve the issue for you too.

Please keep us updated. I'm very interested in doing this LOL.

 

Looks like these bad boys draw some current. A single relay wasn't enough.

 

This is extremely cool.

 

@burnoutboy you got me watching all kinds of youtubes

 

LOL I'm stoked to do this... I should be more worried about getting a B20 and getting her roadworthy again.

 

**** yea....I'm gonna do it. These civic horns are worthless.

 

Now that's funny.

 

I gave up on wiring the horns w/relays.

Instead I found a post on using the existing relay & rewiring the relay.
DIY OE 2-wire to 1-wire horn conversion for EG Civics (using existing relay)
My concern was the author used 2 horn however it appears to work w/4, although I haven't leaned on them for any length of time. They are very loud & are a huge improvement over oem stock single horn. Even wifey thought it was cool. Finding adequate space behind bumper cover/grill was a bit of a challenge & consumed time.

 

I really don't see how it could be hard to wire in 4 horns, the diagram tells you where each wire goes. If you have the 1st gen horns with only 1 wire than that is the power wire, when you bolt it down that provides the ground.

 

At first I was interested in this and then decided that I wanted the old Model A Ford Ooga horn.

Turns out Princess Auto brought in a cheap version that they sold for $9.99 while they stock a higher quality version horn for $69.99.

Doing a little research pointed out that adding a 1 ohm resistor to the cheap ones fixed up the sound to be authentic. Without it it's just a straight screaming oooga as I tested with a couple of wires with alligator clips to my battery.

What I read is kids were putting crappy 1/2 watt 1 ohm resistors inline to get it to sound right and just replacing them any time they fried them (which was anytime they laid on the horn for any amount of time). I'm guessing 1/2 watt is the highest rating they could find readily available for cheap.

Anyways, I ordered for under 9 bucks. They finally came in today from China, took close to a month I think but hey, for less than 20 bucks to have an old time horn for cheap.... I can't beat that.

Anyways, so I soldered one of them inline to the hookup wire on the horn, then took it back down and tested it on my battery with the same wire and alligator clips and sure enough, the single 1 ohm resistor cause just enough delay to get the authentic Ahhooooogaa sound of the old Model A Fords. And being 100 watt, the current won't burn it out no matter how long I lay on my horn.

So I know what I'm going to be doing this weekend and installing my new Ooga horn.

Personally I think the ooga trumps the caddy 4 note horn and is much easier to install on a 95 civic.

 

my civic front clip came with one of those fancy mitsuba horns,it sounds like it has a stuffy nose.....really curious to this happen

 

I want video.

 

TC, something like this?

 

Yeah except the model Princess auto brought in for cheap is red like this:


Wasn't wolo brand, but it was in the reviews of these cheap red ones that I read about the one ohm resistor trick.

Any will do Tony. I just pulled my stock horn and have nabbed the mounting bracket from it and fully prepped the ooga horn. Will take a pic of it in place before I put the bumper back on and then record the video of the horn working after bumper is back on etc.

If the rain and such kill it, I'm only out 10 bucks.

I figure if the weather kills it in the stock horn location, I'll take the trouble to pull the wires back into the engine bay and install a new one where my stock air box used to be.

I carved the insulation out of one of the holes on the plug mounted to the horn to discover it's riveted onto the horn. So I had to file down two spades to be the pin size for the female harness plug.

I think loading the plug up with die electric grease before I stick the spades in then wrap it in electrical tape to hold the wires to the plug should secure and weatherproof it enough without making a mess of the harness plug.

The horn side I'll goober the female spade connectors with the brush on electrical tape as I don't care if I gooberize the horn.
