At a Glance

• Vehicle-specific harness—not a complete remote starter
• Factory-style connection approach for supported applications
• Helps reduce custom wiring where the installation guide allows

Compatibility & What You Need

Designed for supported iDataStart HC and compatible systems. This is ADS-THR-SU3 for remote start, not the different HRN-HRR-SU3 radio-replacement harness.

A compatible remote-start control module and vehicle-specific programming are separate. A T-harness does not guarantee a no-wire installation; follow the current vehicle guide for required analog connections and safety inputs.

Professional installation, vehicle-specific firmware and additional integration parts may be required. Confirm the vehicle year, make, model, trim, ignition type, transmission and existing equipment before ordering; this is not a universal plug-and-play promise.

What’s Included

• ADS-THR-SU3 installation harness
