I'm putting new horns to replace the boring single horn on my 2026 Chevrolet TrailBlazer LS. It's difficult to get to that red tab to remove the clip on the connector sometimes you'll need a small screwdriver to push it off and squeeze the tab connector comes off. If you get someone with small hands they can get in there and get it removed. But you can maneuver it out of there the old horn without removing the bumper and then put the new horn in the original location can you buy replacement horn kit which comes with two horns and a sweater connector you put the second horn right above it and it's much louder sounds great. For me two horns wasn't enough so I'm going to put two extra horns on the passenger side running a wire over there. I ordered a second horn kit Plus and extension cable on Amazon. You look for extra loud horns for GM vehicles. I hope this helps anyone out there. Or if there's any suggestions let me know. I like to know about any other good modifications for the 20-25 or 2026 Trailblazer
