1-to-2 Factory Power Lead Doubler HONDA CRF 250L/300L & Rally 2017-2025

Fits 2017–2025 HONDA CRF 250L, CRF 250L Rally, CRF 300L and CRF 300L Rally

Double your factory accessory power without cutting a single wire. The SRC Moto 1-to-2 Factory Power Lead Doubler plugs into your bike's factory 12 volt accessory connector and splits it into two identical factory-style outputs. Run a GPS or other permanent accessory, and still keep a plug-in point open for an SRC Moto Dual USB or SRC Moto 12 Volt Outlet.

Why you need it

Honda supplies one capped-off 12 volt accessory connector: behind the headlight on the CRF 250L/300L, and inside the left fairing on the Rally models. Once a navigation unit or other device is wired to it, there is nowhere left to plug in anything else. The doubler fixes that.

• Output A: GPS, navigation unit, or other permanently mounted accessory
• Output B: SRC Moto Dual USB, SRC Moto 12 Volt Outlet, or another plug-in accessory

Genuine Honda factory connectors

Every connector on the doubler is the same connector Honda uses on the bike's own accessory lead, so it fits, locks, and seals exactly like the original.

• True plug-and-play: the input mates with the factory connector, and both outputs match it, so any accessory built for the factory lead plugs straight in.
• Positive lock: factory retaining tabs click solidly into place and won't shake loose off-road.
• Weather sealed: factory-style seals keep water, mud, and dust out of the terminals.
• Fully reversible: nothing is cut or spliced. Unplug the doubler and reinstall the factory protective cap to return to stock.

Important: power capacity

The doubler gives you two plug-in points on the same circuit; it does not add power. Both outputs share the factory 10 amp switched circuit (Fuse #5 in the fuse panel on Rally models).

• Keep the combined draw of everything plugged into both outputs under 10 amps (about 120 watts at 12 volts).
• Never install a fuse larger than 10 amps in the accessory circuit.
• Both outputs are live only when the ignition is on.

Easy installation

• Standard 250L/300L: the factory connector sits behind the headlight in a black vinyl boot by the right fork tube.
• Rally models: the factory connector is inside the left fairing, taped to the harness between two vinyl-coated retaining clips.
• Depress the release tab, pull off the protective cap (the part with two green dots), and click the doubler on. Needle-nose pliers help if you can't get your fingers in.
• Route the cables along existing harness and cable routes, clear of the fork tubes, and secure them with the included zip ties.

A printed installation guide is included with every doubler.
