About the iDatastart ADS-THR-TL5

Vehicle-specific T-harness for an iDatastart remote starter

iDatastart's ADS-THR-TL5 T-harness connects their iDatastart CMHCXA0 HC remote start module to your select Toyota-built vehicle. 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.

More details on the iDatastart ADS-THR-TL5

Product Research


Overview: The iDatastart THR-TL5 installation harness is designed to simplify the installation of your iDatastart CMHCXA0 remote start module (sold separately) into compatible 2010 - up Toyota and Scion 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.

Customer Q&A

Crutchfield asked: Why did you buy this?
It seemed like you could do a firmware update without buying a separate module. If that is the case, then it is documented well on the site. [ Paul  Nov 25, 2018 ]
