Installing The Switching Leads: This Kit has two small blue Posi-Locks instead of a standard H4 Coupler. Posi-locks are used to make the HI/LO beam connections to the bike for normal switching. The kit’s yellow wire is LO beam and the white is HI beam. You will be connecting only ONE OEM H4 socket’s hot wires to connect the switching leads. When you lift the fuel tank on the right side frame you’ll find two connectors to the lighting circuit that go to the headlights. Removing the cover from the headstock on the right side will ease installation (requires an allen key). You can disconnect the small OEM loom connectors from the loom harness. You need to cut one of those small OEM loom connectors off leaving about 2 to 3 inches of wire. Remove the old heat shrink-wrap from the connector and you’ll find a black, yellow, red/blue and blue/white wires. Before connecting these wires to the Kit's blue Posi-Locks on the yellow and white wires, slide new heat shrink tube from the kit over the posi-locks and kit wires. When finished connecting to the HI and LO hot wires of the bike finish the job by shrinking the tubing over the Posi-Locks and wires to keep out dirt and moisture.
