Factory horn replacement

Hey all

Trying to replace factory with the PIAA dual superior bass horn. Attached are some images and a couple questions are

- it doesn't show I need a relay.. Correct?
- what do I need to do with the remaining negative wire (green)

First test didn't work.
Thoughts please

Thx

Hi,
I installed these horns a few weeks ago using a kit from agile off-road which included a mounting bracket and wiring harness. I can confirm no additional relay is needed

If you split the positive (brown) wire and run a lead to each positive terminal on the horns Then do the same with the negative terminals to the green wire, they should work

Hmm. It's wired it that way and nothing. Interesting. I might need to check the relay to make sure it didn't get blown.

Thank you though

TX-Newbie, Hope you get your problems solved soon with a minimum of fuss. I've been considering a horn upgrade so I'll be curious to see what you have to say. I like the idea of the Agile Off Road horn kit - particularly if it includes wiring to make the installation easier.

I haven't taken time to understand how to remove the grill. Any comments on that would be appreciated.

ON EDIT: just watched a very short YouTube video on grill removal. Looks like several screws at/near the top edge of the grill, then several spring latches/fingers near the bottom edge of the grill. Is that correct? Hmmm.... ours is a 2010 Interstate, yours is newer and may be different.

Four years ago I bought a simple 15-bucks bass horn in local store, and simply connected it to factory horn wires, neutral and positive. From then and on I can scare any pedestrian with two-tone scream )))

Hey all

I had some loose wires and now it works with no problem. Sounds much better than stock.

I would follow what @schmitte did though which is get it from agile so you get the bracket and wires. Will make it much easier

Thanks all for the help
