Wiring Harnesses, Cables & Connectors
About Wiring Harnesses, Cables & Connectors
Audio and accessory wiring parts link the pieces of a bike's electronics together and supply power for chargers. The listings include wiring harnesses, radio and body control connector kits for Harley-Davidson models, quick-disconnect power cables, USB charging cables and adapters, an action camera harness and a charging kit for Polaris. Riders buy them to add USB power for a phone or GPS, to plug in audio without cutting factory wiring, or to repair damaged cables.
The first split is model-specific or universal. A harness or connector kit made for your bike plugs in without cutting wires, while universal cables need splicing and sealing. Next, match the connector: USB-C, micro USB and standard USB are all listed, along with adapters between them, and a battery charger cable with an SAE connector. Check the cable length, from 12 inch phone cables to 58 inch power cables, and use fused power for anything connected to the battery. Seal connections against water, and pick your bike in the Ride Finder at the top of the page for model-specific harnesses.
Brands here include Jims, Jensen, Custom Dynamics, Saddle Tramp and HogTunes. For the parts these connect, see Amplifiers, Speakers and Headsets & Intercoms. The wider group is Audio, Communication & Navigation.
FAQs on audio wiring, cables and connectors
What is the difference between USB-C and micro USB charging cables?
USB-C is the newer, reversible oval connector found on current phones and devices, and micro USB is the older, smaller trapezoid shape. Check the port on your phone or GPS, then choose the matching cable or use an adapter. Adapters are listed here for converting between them.
Will a USB charger run down my motorcycle battery?
A charger wired directly to the battery can draw a small current even when the bike is off, and a phone left charging can empty a battery over time. Where you can, connect it to a switched power source, use the fuse the kit supplies, and unplug devices when parked.
Do I need a model-specific harness for an audio install?
A model-specific harness plugs in without cutting factory wiring, which makes the job cleaner and easier to undo. Universal wiring needs splicing and sealing and takes more care. Check the listing for the model and year, and use the Ride Finder to narrow the list.
What should I check before replacing a damaged wiring harness?
Match the model, year and options, disconnect the battery first and inspect the connectors for corrosion or bent pins. Follow your service manual for routing and for the connector order. A damaged connector can look like a failed harness, so check it before buying.
How do I protect electrical connectors from water?
Use sealed connectors or boots, keep the plugs fully seated and apply dielectric grease where the maker recommends it. Route cables away from heat and moving parts, and secure them so they cannot rub through. Moisture in a connector is a common cause of faults.
