Remove the ½” acorn nut that attaches the stock horn and bracket. Remove the horn & bracket assembly from the stud it is mounted to and unplug the 2 wires. Next remove the seat. Assemble the hose w/ wire loom and relay onto the horn set as shown in photo (1). Plug the two wires from the loom onto the relays terminals 30 & 87 (see the wiring diagram provided). Secure the relay to the upper hose as shown using one of the small cable ties

. Attach the hose from the loom to the “Y” fitting. Adjust the wires, hose and loom as shown and secure with a small cable at (1A). Attach the wires from the original horn to the remaining terminals #85 and #86 (NOTE: it makes no difference which wire goes to which terminal). Install the horn assembly using two (2) of the four (4) large washers provided behind the horn mounting bracket. Replace the stock acorn nut with the one supplied and tighten securely. The horns should be horizontal or the front angled downward slightly. Check to see that the horns have at least 1/4" clearance between the engine, shift linkage and choke knob. If necessary add the remaining two (2) large washers behind the horn mounting bracket to get the required ¼” clearance between the long upper trumpet and the cylinder head. Use a small cable tie to secure all wires as shown at arrow (1B). Route the wire/hose loom up under the fuel tank, over the rear cylinder head and towards the rear where you are mounting the compressor, (see below) you can cable tie the loom to any existing wires or hoses. Take any slack out of the loom, keeping it up against the frame and away from the engine or exhaust, using several of the small cable ties provided
