How to Install a Horn on a Golf Cart
The point of a horn is to be heard. (a boat horn image by Ana Stefanovic from

Horns give a golf cart presence on the golf course and off. And because golf carts use has expanded far beyond the game of golf, horns are more in demand. Some horn sounds are angry, some are loud, others make little beeping noises and some play music. Whatever sound you choose for your horn, let it make a statement about who you are.

  1. 1

    Install a horn for the golf cart that matches your personality. There are plenty of aftermarket models to choose from at auto parts stores and other retailers.

  2. 2

    Find a place near the steering wheel of the golf cart to install the horn switch. Drill a hole into the dash and drop the horn switch into the hole. The switch is push-button, so make sure the fit is snug. It is better to widen the drilled hole a couple of times than to drill the hole too big the first time. You need to thread the wires through the hole and pull the switch until is sits firmly in place.

  3. 3

    Run the ground wire from the horn switch to the ground at the fuel gauge. Remove the screw from the fuel gauge ground and place the horn ground wire on top and screw the assembly together again. Both ground wires are black in colour.

  4. 4

    Spread the other wire from the horn switch to the right side of the relay. The relay switch needs to be mounted under the dashboard of the golf cart. The relay is a solid piece of plastic that attaches under the dash with two screws. Use a drill to make two holes in the underside of the dashboard. When placing the relay, run the wires under the floorboard to the fuse box, the control box and the horn. This wire running from the horn switch to the relay is brown with a black line. This wire is the power wire. Run the power wire to the terminal of the relay trigger coil on the right side. The right side is the side where the relay opens and closes.

  5. 5

    Take the brown/green wire and run it from the left side of the relay to the fuse and then from the fuse to the control box. All of this is under the seat of the golf cart. The fuse is glass and the filament inside looks like a wire hair. There is a plastic holder the fuse snaps into in the fuse box located under the seat. On each side of this plastic fuse holder is a screw to attach the brown/green wire. You will need to cut the wire, remove some of the sheath on each end and attach the two different wires to the fuse holder to get a complete circuit connection. The wire from the relay runs under the floorboard and under the seat reaching the fuse box and the control box.

  6. 6

    Attach the other power terminal on the right side of the relay to the horn; this wire can be any colour. Mount the horn to the roof of the golf cart. Run this last wire from the power terminal on the relay up the support pole for the roof of the golf cart. This is a single horn wiring pattern. In a two-horn wiring pattern, the second horn splices into the wire that runs from the second wire terminal on the relay to the first horn. The splicing creates a circuit for the electricity to power the second horn to blow.

Tips and warnings

  • When you remove the golf cart horn from its packaging, lay the pieces out on a table and align them properly according to the directions. Visualising helps the installation go smoother.
  • As with all electric repairs, make sure the power source is disconnected.
