Description
iDatalink Maestro ACC-ABP-HD2 Harley-Davidson Factory Amplifier Bypass Harness
On a 2014+ Harley, replacing the radio and replacing the factory amplifiers are two different jobs. ACC-ABP-HD2 handles the amplifier-bypass side.
Supported Harley audio packages can have multiple factory amplifiers in the system. If the build is moving to aftermarket amplification, those OEM amps have to come out of the signal path cleanly. ACC-ABP-HD2 provides the plug-in bypass connections for supported motorcycles without cutting the factory harness apart.
iDatalink supplies four amplifier-bypass plugs, allowing the kit to handle supported systems equipped with up to four compatible factory amplifiers. The bike may have fewer than four; the actual factory audio package decides how many bypass connections are used.
Radio Integration Does Not Automatically Bypass the Amps
HRN-RR-HD2 can be the correct harness for the 2014+ Harley radio-replacement side and still leave the factory amplifiers as a separate issue. If those amps are being removed, ABP-HD2 is the part that addresses their wiring path.
That separation matters when the parts list is built. A new radio can power up and the Maestro integration can work while the audio system is still incomplete because the factory amplifiers were never properly bypassed.
What It Does—and What It Does Not
ACC-ABP-HD2 preserves the factory wiring while bypassing the supported OEM amplifiers. It is not a DSP, Maestro RR/RR2 module, amplifier-replacement processor or aftermarket amplifier, and it does not provide RCA output or tuning.
The exact motorcycle, year, factory radio, speaker package and factory amplifier count must match before adding it to the system.

Where this fits in the build
This is a system-control or DSP component. The correct choice depends on the signal path, channel count, routing, retained features and the rest of the amplifier and speaker plan.
