Thank you for choosing DENALI
We know you would rather be riding your bike than wrenching on it, so we go the extra mile to make sure our instructions are clear and as easy to understand as possible. If you have any questions, comments, or suggestions don’t hesitate to give our gear experts a call at 401.360.2550 or visit WWW.DENALIELECTRONICS.COM
Please Read Before Installing
DENALI products should always be installed by a qualified motorcycle technician. If you are unsure of your ability to properly install a product, please have the product installed by your local motorcycle dealer. DENALI takes no responsibility for damages caused by improper installation. Caution: When installing electronics it is extremely important to pay close attention to how wires are routed, especially when mounting products to the front fender, front forks, or fairing of your motorcycle. Always be sure to turn the handlebars fully left, fully right, and fully compress the suspension to ensure the wires will not bind and have enough slack for your motorcycle to operate properly.
Installation Tips
We strongly recommend using a medium-strength liquid thread locker on all screws, nuts, and bolts. It is also important to ensure that all hardware is tightened to the proper torque specifications as listed in your owner’s manual. For included accessory hardware please refer to the default torque specifications provided below. Inspect all hardware after the first 30 miles to ensure proper torque specifications are maintained.

Hardware Sizing Guide
Not sure what size bolt you have? Use this ruler to measure screws, bolts, spacers, etc. Remember, the length of a screw or bolt is measured from the start of the “mounting surface” to the end of the screw, so only include the screw head when measuring countersunk screws.DENALI DNL.WHS.12400 Wiring

Wiring Harness Overview
Our Standard Single Intensity Harness features high-quality waterproof components and a clever HotSwap™ design that enables an effortless swap from the standard Single-Intensity relay to our Dual-Intensity DataDim™ Controller (Sold Separately). If adding the DataDim™ Controller upgrade now, jump ahead and read Section 5 before returning to Section 2.2. If not, continue to Section 2.2 with peace of mind that you can always upgrade later, without having to rewire the lights.
Note: The DENALI harness with pods connected is 72 inches in length. DENALI Harness Extensions are available for purchase if extra length is required.

Routing The Wiring Harness

  • Step One: Find a suitable location near the battery to store the Single-Intensity Relay.
  • Step Two: Begin routing the harness towards the mounted light pods. Secure the harness to the vehicle’s frame along the way with the included zip ties. Be sure to avoid any moving components such as fan blades or suspension. Plug the light pods into the base harness.
  • Step Three: Route the switch wire to the location where the switch will be mounted and secure it to the vehicle using zip ties. See Section 3 for switch mounting options.

Tapping Switched PowerDENALI DNL.WHS.12400 Wiring Harness for Driving
Lights Standard Powersports-fig5

  • Step One: Two examples of possible switched power sources are the low beam and tail light, however there are many other possible sources vehicles. The simplest way to identify switched power is to use a test light to probe connectors/wires while cycling the ignition. A clean switched power source will only be live when the ignition is cycled “ON”, it should lose power when the ignition is cycled “OFF”.
  • Step Two: Once a proper switched power source has been identified use the included Posi-Tap to tap the white trigger wire into the identified switched power source.

Connecting To The BatteryDENALI DNL.WHS.12400 Wiring Harness for Driving

  • Step One: Remove the fuse from the fuse holder.
  • Step Two: Access the vehicle’s battery and disconnect the negative (-) and positive (+) terminals.
  • Step Three: Connect the DENALI wiring harness to the battery via the ring terminals, be sure the red wire lead with the fuse holder in-line goes to the positive (+) terminal of the battery.
  • Step Four: Re-install the fuse into the fuse holder.

Note: When possible, place the fuse holder in an easily accessible location for convenient service in the event of a blown fuse.

Mounting The Switch

  • Step One: Clean and prep the mounting surface and the bottom of the switch using an alcohol swab. Allow surfaces to fully dry.

  • Step Two: Peel away one side of the backing from the adhesive pad and adhere the pad to the bottom side of the switch.
    Note: To ensure a stronger bond use a heat gun to warm the tape before applying to the surface.

  • Step Three: Peel away the remaining backing from the adhesive pad and adhere the switch to the mounting surface using moderate pressure.

  • Step Two: Use a 9.5mm or 3/8” drill bit to drill the mounting hole into the panel.
  • Step Three: Unscrew the Switch Cap from the Switch Base.
  • Step Four: Pass the stem of the Switch Base up through the drilled hole and secure the switch into place by reinstalling the Switch Cap to the Switch Base.

DataDim™ Controller Upgrade

DENALI 2.0 Light pods are equipped with a dedicated 3rd-wire dimming circuit so we can use an external signal to reliably control the intensity of the LED chip at the source. Plug in our Dual-Intensity DataDim™ Controller to enable the DENALI lights to switch between half and full intensity with your vehicle’s original high beam switch.

  • Step One: Unplug the Single-Intensity Relay from the Base Harness.
  • Step Two: Plug the Dual-Intensity DataDim™ Controller into the Base Harness.

Tapping The High BeamDENALI DNL.WHS.12400 Wiring Harness for Driving

  • Step One: Plug the blue Dual-Intensity Trigger wire into the bullet connector at the base of the On-Off Switch.
  • Step Two: Use a test light while toggling the vehicles high beam switch to identify the wire which receives power upon high beam activation.
  • Step Three: Once the high beam trigger has been identified, use the included Posi-Tap to tap into the wire.

Note: Some vehicles are equipped with LED headlights or other lighting systems that do not provide a clean 12v high beam trigger signal. See Figure 5.1 for an overview of our independent dimming switch.
