About the iDatastart HK5

Vehicle-specific T-harness

iDatastart's ADS-THR-HK5 T-harness connects their iDatastart CMHCXA0 HC remote start module to your select Hyundai or Kia vehicle with standard key ignition. This T-harness plugs into your vehicle's electrical databus system, allowing you to start and stop the engine remotely, and control some basic factory security functions as well. Some wiring may be required — one to four connections, typically. You can identify your vehicle in our fit guide to see if this harness is compatible. Warranty: limited lifetime.

  • 24" Main T-harness (inline 30A ATC fuse)
  • 29" 10-Pin harness
  • 29" 12-pin harness

Compatibility: The iDatastart ADS-THR-HK5 installation harness is designed to simplify the installation of your iDatastart CMHCXA0 remote start module (sold separately) into select 2010-up Hyundai and Kia vehicles. Click here for a list of compatible Hyundai and Kia vehicles.

Installation: The iDatastart kit includes various vehicle-specific harnesses designed to provide a direct connection into your compatible vehicle while connecting to the remote start module on the other end, saving you considerable time and effort. The main T-harness interfaces into the ignition system, providing direct connections for the Starter, Ignition, and Accessory wires. Other functions may include Door Lock operation, Parking Light flash, Horn Honk, as well as Door, Hood, and Trunk pin switch activation (individual functions will vary, please see vehicle specific information for details).

Note: The included harnesses will take care of the bulk of required wiring, but some hardwiring into the vehicle's wiring system will still be required.

What's provided could be better. It's enough to get the job done. I installed it in 20 minutes after programming. Enter
