About the iDatastart ADS-THR-TL5

Buck Pomerantz

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.

  • 14" Main T-harness
  • Three 10" extension harnesses (A/B/C)
  • 25" OBDII T-harness
  • 27" 7-Pin T-harness
  • 64" 4-Pin harness
  • 28" 12-Pin harness
  • 27" 2-Pin harness

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.

This will fit the vehicle mentioned. If you purchase the recommended T-harness the only splicing "that may" be required is for the headlights to blink upon remote start. Other then that easy peasy. I've installed 3 of the idatastart remote starters found it to be extremely easy when using the recommended T-harness
david  Mar 08, 2022
What additional wiring is needed to install this that there harness doesn't cover?

The harness is fine problem comes from the module that needs to be connected to the computer to download a certain program specific to the car, no matter how many times itried i couldnt download the program to the module, i think it should have been done in crutchfield so its going to be an esy install.
melquiades  Feb 22, 2020
Every thing that you need is included. This is a very simple install and if you need customer support they are the best. Had mine installed and running in a couple of hours.
james  Feb 22, 2020
I installed it in a 2019 SR5 4Runner and had wires left over. Its a universal kit that fits different vehicles. So your answer is none. Watch a YouTube video for your specific vehicle the harness clips are bulky. Hope this helps..
