Installation does not interfere with removal or installation of stock detachable windshield on Road King Models. This kit includes a 12-Pin Wiring Adapter that places control of the driving lights on the motorcycle’s Accessory switch on '98-'13 Electra Glides and Street Glides. If you already have accessories wired to this switch, you will have to choose an alternative wiring method (sold separately). Alternatives include replacing the stock Accessory switch with a Küryakyn Double Rocker Switch, P/N 2201, or adding a Kuryakyn Universal Driving Light Wiring Relay Kit, P/N’s 2202, 2203 or 2328. If you have an empty switch location on the dash, you could purchase an OEM switch from an authorized H-D dealership.
