Where this fits in the build
Vehicle-specific and open-air equipment should be chosen around fitment, environment, placement and the output needed where the system will actually be used.

ARC Audio HD-FH2024-RCA 2024+ Harley-Davidson Installation Harness
The 2024+ Street Glide and Road Glide changed enough that treating the wiring like an older Harley creates extra work fast. The HD-FH2024-RCA is ARC Audio’s plug-and-play wiring package for getting a MOTO 720 or MOTO 800 amplifier and PSM-Pro DSP into the new-generation factory-amplified bike without cutting up the factory speaker wiring.
This is more than an amp power kit. It handles the signal path from the speaker pods to the DSP, routes amplified output back to the pods, adds the under-seat P&A connections, and includes the amplifier power/ground harness. ARC also corrects the 2024+ Harley speaker-pod polarity reversal inside the harness, so the aftermarket speaker terminals can be connected normally instead of cutting and flipping factory wires.
Where this fits
- 2024+ Harley-Davidson Street Glide with factory-amplified radio
- 2024+ Harley-Davidson Road Glide with factory-amplified radio
- ARC Audio MOTO 720 amplifier
- ARC Audio MOTO 800 amplifier
- ARC Audio PSM-Pro DSP
- Select other aftermarket amplifiers and DSPs where the same signal and power architecture is appropriate
If the goal is a complete ARC system, this is the wiring piece that ties the amplifier and DSP installation together. It does not replace the DSP or the factory-integration module by itself; those pieces still need to match the exact Harley audio system.
Why this harness instead of building it wire-by-wire
You can fabricate power, signal and speaker-return wiring from scratch, but on these bikes that means more splices, more routing decisions and more chances to get the pod polarity wrong. ARC breaks the integration wiring into four individual sections so the signal runs can be routed where they actually fit in the fairing instead of forcing one bulky loom through the bike.
Included
- Pre-loomed, terminated 100% copper 8-AWG main power/ground harness with inline fuse
- Plug-and-play input/output signal integration harness set
- Pre-loomed P&A harness with +12 V accessory, +12 V constant and ground
- Adhesive-backed hook-and-loop fastener for amplifier mounting
- Blue butt connector for the accessory lead
- 10 zip ties
Installation details that matter
- Color-coded RCA wiring uses standard grey and white channel identification
- Designed around the factory-amplified 2024+ Harley Touring audio architecture
- OEM-style looming and harness preparation
- Corrects the factory speaker-pod polarity arrangement inside the harness
- No cutting or splicing of the factory speaker-pod wiring is required for the polarity correction
Fitment note: verify the exact motorcycle, factory radio and amplifier configuration before ordering. Harley changed audio architecture across this generation, so the wiring kit and DSP/integration path need to be matched as a system.
