Sometimes we as well need to warn animals of our approach. Occasionally our horns malfunction through the steering wheel contact switch, or nosotros simply want a backup system. Universal horn buttons can provide that actress assurance. They tin can be installed past whatsoever vehicle possessor, using a few steps and simple tools.

Step i

Buy your universal horn push kit. Note whether you want a double wire horn push or a single wire push button. The unmarried wire push button will require only one wire connection, which will be a hot (positive) wire to the fuse block or to original horn wire in the horn wiring loom. The single wire push requires that y'all mount the button directly into the metallic of the dashboard frame or another metallic source. The double wire button will require grounding the extra wire to the chassis or some part of the metal frame.

Step two

Place the vehicle in park or neutral with the emergency brake prepare. Disconnect the negative bombardment cablevision with a socket and wrench. Heighten the hood and locate the original equipment horn. In that location will be just one wire attached to a tang protruding from the horn, which will be the hot wire. Follow this wire back toward the dashboard every bit far as yous can. You might take to slit the loom to locate it. Detect a good spot to cut the wire with wire strippers. Apply the wire strippers to strip both ends, leaving virtually a half inch of bare wire.

Step iii

Take an in-line fuse, with wires fastened at both ends, and place it betwixt the cut wire. Twist one end of the horn wire to ane stop of the in-line fuse wire by hand. Twist a wire nut on the joint. Practice the same to the other end, but add the long kit wire into the joint, twisting three wires together and twist a wire nut onto the connectedness . You at present have i unmarried wire connected with two wire nuts, with a fuse in between, and a new hot wire coming out of it. Tape whatever excess wire slack to the chief wire loom.

Step 4

Run the single kit wire up the loom, taping it to the loom with electrical tape as you move toward the back of the engine. Find a grommet in the firewall and push the wire through. Go to the driver's seat and decide where to mount your horn button. Drill two holes that match the width of the push button mounting frame in the metallic part of the dashboard. Drill i more larger hole in the center of the two mount holes. Be conscientious not to drill into any component on the other side of the dashboard.

Stride 5

Run the wire upwards through the middle hole toward you and spike it to the wire on the horn push button. You might have a female jack on the push wire or a spade connector. Use the kit parts to bring together the two wires by stripping the stop of horn wire and attaching the proper connector. In one case connected, align the horn push button-mount over the drill holes and twist 2 self-tapping screws into the dashboard past hand. Tighten the screws with a Phillips screwdriver.

Stride six

Connect an additional wire to the back of the horn push button if it has 2 mail service connectors. This will be a footing wire. Run the ground wire inside the dash board. Crimp a screw eyelet on the end of the wire. Look for a good ground source underneath the dash, such as a small nut or bolt attached to the frame. Remove the bolt with a socket or use a screwdriver to remove the screw. Connect the eyelet to it, and screw the commodities or screw dorsum in with a socket or screwdriver.

Tuck upwardly any excess wire into the dashboard, securing it with electric tape so it does not fall down or snag on anything. Reconnect the negative battery cablevision and test the horn functioning.
