Working in conjunction with iDatalink's Maestro ADS-MRR or ADS-MRR2 module, iDatalink's HRN-RR-HD2  wiring adapter allows you to connect a new iDatalink-ready radio in select 2014-20 Harley-Davidson motorcycles. You'll retain the use of your handlebar audio controls, plus you'll gain the ability to program two functions for each button. The module also allows you to view vehicle information, read and reset engine codes, and view select performance gauges including H-D Track Pack gauges.

This harness also turns on your factory amp (if present) and provides the outputs necessary to install a radio with navigation functions, including parking brake and speed pulse. If your new radio has a second camera input, you'll retain your Front Camera Auto Control feature. You can use this harness and the iDatalink module to install a non-iDatalink-ready radio, but you'll only retain your handlebar audio controls, and none of the other features.
