Vehicle-specific harness for 2013+ Chrysler group

The iDatalink HRN-HRR-CH3 harness connects a Maestro ADS-MRR or ADS-MRR2 module to select 2013 and newer Chrysler, Dodge, Jeep, Ram, and Fiat vehicles that use a 52-pin radio plug. It enables installation of a compatible aftermarket receiver with an iDatalink port while retaining factory steering wheel audio controls and amplifier output. The harness is designed for owners who want to upgrade their head unit without losing integrated vehicle functions.

Sustained operation with factory systems retained

Once installed, the harness maintains continuous communication between the Maestro module and the vehicle data bus, preserving steering wheel controls, factory amplifier integration, and convenience features such as OnStar, SYNC, and Uconnect where equipped. Engine performance data streams to the aftermarket touchscreen during normal driving, and the connection remains stable through ignition cycles and extended use without requiring reconfiguration.

Replaces the factory radio plug for aftermarket

This harness replaces the original 52-pin connector when installing a Maestro-compatible receiver from brands such as Alpine, JVC, Kenwood, Pioneer, or Sony. The upgrade is worthwhile when the owner wants a modern touchscreen with vehicle data display while keeping steering wheel controls and the factory amplifier. It is not for vehicles without a 52-pin radio plug or for installations that do not use a Maestro RR or RR2 module.

Questions about this item

Does the 52-pin radio plug connection generate any extra heat or noise during continuous use?

The harness is a passive wiring adapter with no active electronics, so it adds no heat or audible noise regardless of how long the system runs.

What additional module must I already own for this harness to function in my 2013+ Chrysler vehicle?

You need a Maestro ADS-MRR or ADS-MRR2 module; the harness alone cannot communicate with the vehicle data bus.

Will the ADS-MRR module included here still work with my older 2006-era GM or Ford vehicle if I move it later?

Yes, the ADS-MRR module supports select 2006-up Chrysler, Fiat, Ford, GM, Honda, Subaru, Toyota and VW vehicles when paired with the correct vehicle-specific harness.
