As others have posted about the 2015+ models, getting at it from the bottom of the car was easy and straightforward. Here's some pics I took of the "El Grande" install.
New "Get outta my way" horns next to the OEM "meep meep".
Only takes 5 bolts and a 10mm socket to get access from the bottom of the car. Jack from one side and put a jack stand under for safety.
What the stock setup looks like. One 12mm bolt to remove it from the support.
The two connections to the stock horn. The longer cable with the black connector is the ground wire that connects to the bracket. The shorter yellow connector goes to the pigtail male connection.
The new horn all bolted up to the stock bracket, horns angled down and a single ground connector attached to the brackets.
That was easy! Like others have said, the pigtail cable you need to create only really needs to be 8 inches long at the most. There's plenty of wire on the stock harness. The whole job took like 30 minutes, mostly because I read through this thread before attempting. Thanks for the help!
I just installed the EL Grande Fiamm horns. There were a couple of minor differences. I have a 2015 SV.
There were more than 5 bolts needed to be removed and a few plastic plugs.
The horns had 2 connectors instead of the one shown in your photo. I made a couple wires with a circle connector on one end and a female spade connector on the other. I plugged them into the spade on the right and ran it through the bolt in the center of the horns.
I wish I made a 4 inch wire for the power side, 8 inches is way too large.
On the factory harness, the long wire was the ground (with a black connector) and the short wire was power (with a red connector). Both connectors were covered in some grease like stuff I had to wipe off.
Im all done, I have a much better sounding horn now.
