Drahcir495 Posted January 25, 2020 Share Posted January 25, 2020 Hey guys. I am looking for new horn options for the XJ. I am not looking to get one of those train horns, just something to let them know I am here. I would like to know what you all are using and what you recommend. I am missing the one wire for the factory horn button some where in the steering column, so I have nothing right now. Link to comment Share on other sites More sharing options...
eaglescout526 Posted January 25, 2020 Share Posted January 25, 2020 Which wire? The horn wiring goes through the whole turn signal switch assembly. Link to comment Share on other sites More sharing options...
Drahcir495 Posted January 26, 2020 Author Share Posted January 26, 2020 I think the black one. Only one wire has come through Link to comment Share on other sites More sharing options...
eaglescout526 Posted January 26, 2020 Share Posted January 26, 2020 Three spoke "sport" or the two spoke "wagon" steering wheel? Link to comment Share on other sites More sharing options...
FrankTheDog Posted January 26, 2020 Share Posted January 26, 2020 Most XJ’s come with dual horns. 400hz and 500hz switch your 500 to a 400. That made mine more noticeable to me. Running them off a relay may help too. More current going to the horn. Link to comment Share on other sites More sharing options...

I know the button just needs ground out to the center of the column to sound the horns. There is already power going to them, just pushing the button completes the horn relay circuit to switch power to the horns. Link to comment Share on other sites More sharing options...
coheed Posted February 16, 2020 Share Posted February 16, 2020 GM four note horn. They are loud enough that people jump when I have to honk at them. I put one on most every vehicle I own. Have to add an extra relay for two of the horns, but that's fairly simple. Go to the junkyard and find yourself a Buck, Cadillac, or Oldmobile from the late 70's to the early 90's with high trim packages and look for one with four different horns. Typically on Buicks and Cadillacs they are mounted in the engine bay in the front corners. The ones I have on my Comanche came from a Buick Reatta.

Go to the junk yard and look for the big bodied Caddys from the 80s/early 90s. Tucked inside the fenders at the front there are 4 horns, two on each side of the vehicle. They're easy to yank out. Pull the wiring harness for them as one piece, it is a green wire that hooks all four horns together. Splice the harness to your stock harness (can use a male spade connector on the Caddy harness to plug it into your stock harness). Each of the horns mounts with one bolt, find convenient spots for them, drill holes, clean paint off around mounting bolt (the horns ground through the mounting bolt). Sounds like a train horn with good volume. I swapped them into my XJ after I drowned the single stock horn. I also relocated the horns to beside the air box to get them out of the water. It is nice to have multiple horns in the event I drown one again, I will still have a functioning horn. Was a nuisance when I found out my single horn was dead in a situation when I needed it. I did a similar "horn mod" using two horns from a mid-60's Buick Electra 225. They do get people's attention and sound more like a bus than a car. Good idea mounting them out of the weather. I mounted them in the stock locations with the bells facing down to keep the H2O out. So far so good. Link to comment Share on other sites More sharing options...

There is already power going to them, just pushing the button completes the horn relay circuit to switch power to the horns. To expand on this: The black wire you have is the only wire you need. The circuit is powered up, but has no ground for the relay. The horn button closes the ground circuit, actuating the horn relay. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted February 18, 2020 Share Posted February 18, 2020 I added dual horns to my truck when I did the Waggy header, I spliced them both to the stock horn wire on the driver side..... then I found the second horn wire already there on the passenger side.
