I have a 2012 Sport that I just put the PIAA dual low tone horns on. I used the automatic transmission cooler tabs with a home made bracket behind the grill, because I have a six speed. I took the stock horn off, and plugged the home made harness in. The are louder in front of the JK, but quieter in the cab because the aren't under the hood anymore. I just plugged them in, and they work fine with no relay.

I have a set of PIAA horns coming to replace my wimpy stock horn. The question I have is about the wiring. Some say paralell.....some say in series. Now I am not sure and I really don't want to burn out a relay or cause some problem with the remote start or alarm system. Some say include a relay. Some say the stock setup will handle the two horns. If so.....which way to wire them so I don't blow the stock wiring....Anyone done this for real? Feedback needed please. Include a link to a write up with pics maybe???
Thanks!

I just installed a dual horn setup using a 5 pin relay. This replaced the stock horn completely.
(If you use a 4 pin relay, put both horn positives on post 87)
Post # 30: Fused power from the battery
Post # 85 & 86: Wiring from stock horn, to these (doesn't matter which posts)
Post # 87: Wiring to the new horns (positive posts)
Post #87a: Leave off
Then the open posts of the horns, to ground.

Like this:
87a should be hot when the relay coil is de-energized. How did you deal with that?

Works well. Both horns sound with the push of my (orig) horn button.
Maybe I have a defective relay.
I've corrected the previous post. Thanks for pointing that out.
