About the iDatastart ADS-THR-TL7

Vehicle-specific T-harness for an iDatastart remote starter

iDatastart's ADS-THR-TL7 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.

What's in the box:

  • 12" Main T-harness
  • 31" Secondary T-harness
  • 58" 2-Pin harness
  • 29" Single-wire harness
  • Five 6" individual wires pinned for Molex plug
  • JS5 2-pin jumper plug

Remote start

Installed 2 days as advertised. Installation was in less than 2 hours...very clean installation...worth installation cost...

Pros: Need to have AC running during the summer when traveling with my dog. Programmed to 35 min.s run time for stops. Will give it a true test in June and July.

Cons: None yet!

More details on the iDatastart ADS-THR-TL7

Product Research


Overview: The iDatastart THR-TL7 installation harness is designed to simplify the installation of your iDatastart CMHCXA0 remote start module (sold separately) into compatible 2010 - up Toyota and Lexus PTS (Push To Start) 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.
