On my newly purchased 2000 Cherokee XJ the horns are pathetic. I've purchased a set of the four note Cadillac Seville horns to install. My Achilles Heel has always been electrical and I'm at a loss as to how to hook these up using the original horn button. Not sure the original fuse and relay can handle the new set-up. My thought is an add-a- fuse tap into the original horn fuse slot and increase to 20 amps from 15 take that to a beefier relay and pigtail the power to two pair of horns? Thanks in advance.

 

Just connect them to the original horn wires.

 

Use the original horn wires to trigger a relay that powers your new horn.
