ADS HRN-SR-GM3

The iDatalink Maestro HRN-SR-GM3 is a vehicle-specific, plug-and-play installation harness engineered to work seamlessly with the iDatalink Maestro SR radio replacement module in select General Motors (GM) vehicles.

When upgrading to an aftermarket head unit, factory electronics like steering wheel controls and basic vehicle integration features are tied into your car’s factory wiring network. This T-harness acts as a clean bridge, plugging directly into your factory connectors on one end and connecting to the Maestro SR module and your new aftermarket stereo on the other—eliminating the need to cut or splice stock wires.
