88mjblue Posted January 24, 2015 Share Posted January 24, 2015 Passenger side, picture is looking through grill, this is near the vacuum canister. pink wire not plugged in to anything. Factory fog light harness? I tried tracing it back, it goes near back of headlight plug and links up with loom near battery. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted January 24, 2015 Share Posted January 24, 2015 That single wire is for the horn . There should be one on the other side as well . I'm not sure as to wether or not some came with one or two horns from the factory . Link to comment Share on other sites More sharing options...
88mjblue Posted January 24, 2015 Author Share Posted January 24, 2015 I checked the other side for another similar plug and found the horn there, but no horn on the passenger side, thanks for the reply. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted January 24, 2015 Share Posted January 24, 2015 You can add another horn if you like . There are different tone horns that you can use if you are not happy with your current setup. Link to comment Share on other sites More sharing options...
FrankTheDog Posted January 24, 2015 Share Posted January 24, 2015 I added the horn to mine, it also only came with one. Most XJ's came with two, they are 400Mhz and 500Mhz. It sounds pretty cool when you use two 400Mhz horns. Link to comment Share on other sites More sharing options...
88mjblue Posted January 24, 2015 Author Share Posted January 24, 2015 Interesting, I was not aware of this. I will add "horn" to my junkyard list. Any way to identify a 400Mhz horn? Link to comment Share on other sites More sharing options...
Minuit Posted January 24, 2015 Share Posted January 24, 2015 If it's a factory piece, it should have "Low" or "Low Tone" somewhere on the horn itself. I grabbed a pair of horns from an '01 XJ last time I was in the junkyard. Sounded a lot better than the Autozone special that knocked itself out of tune. 96- XJ horns have Signal-Tone molded into the plastic, and 97-01 horns are made by Bosch.

FrankTheDog Posted January 24, 2015 Share Posted January 24, 2015 Mine said 400Mhz right on it, that's how I knew. I part out XJ's so I always have useful stuff hanging around to use. Link to comment Share on other sites More sharing options...

Motorcharge Posted January 25, 2015 Share Posted January 25, 2015 That single wire is for the horn . There should be one on the other side as well . I'm not sure as to wether or not some came with one or two horns from the factory . Some did. My 92 XJ only has one and my 90 only had one, but both my 88 and 89s had two and my MJ has two. It's a single wire because the bracket acts as the ground. I wasn't aware there were two different tones though. Link to comment Share on other sites More sharing options...
