removing/installing the horn. The thick bracket is located closest to the firewall just behind the clutch line and mounts with 3 10mm screws to the frame rail and 1 or 2 bolts going through the edge of the battery tray into the bracket. The horn is obviously attached to that. The single grounding wire for the horn goes through one of the bolts along the frame rail. The wire for the horn itself may be on a plug but can't recall. I relocated my horn into the fender area since I was repainting the engine bay anyways. Hope this helps
