Installing the Hella Horns on a 2007 Subaru Impreza WRX using the GrimmSpeed BroTie and GrimmSpeed wiring harness.
We followed the instructions for the wiring harness from GrimmSpeed’s website – linked below. Install time was roughly 20 minutes and did not require removal of the bumper, just two trim pieces.

Over a year late too the vid so I’m not really expecting a reply but… with the second horn, the one lower on the right in the vid. Do you just leave that as is and replace the middle one with the bracket and Hellas? I got my grill of yesterday about to install them in my bugeye and saw the second horn and had a little brain fart cause I’d never seen it addressed in a video. I should only be removing the center horn and running the positive wire of the harness to the oem plug and the ground to where the harness bolts on, right?
Guys do you have a link for the same wiring harness that you used in the video please
Would this fit on my 2016 wrx?
What is the tool called that you use to undo the clips from the bumper
do you need to install the voltage relay if you're using the grim speed harness?
Are you still able to remove the second stock horn with the bumper on?
