About the iDatastart ADS-THR-HA2

Vehicle-specific T-harness for an iDatastart remote starter

iDatastart's ADS-THR-HA2 T-harness connects their iDatastart CMHCXA0 HC remote start module to your select Honda-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:

  • 28" Main T-harness (two inline 30A / one 10A ATC fuses)
  • 12" 7-pin T-harness (green plugs)
  • 24" 20-Pin to 8-pin harness (inline 5A ATC fuse)
  • 29" 12-Pin harness
  • 29" 10-Pin harness
  • 29" 6-Pin harness
  • Two 8" optional terminal wires (pinned for Molex plug)

It Works

I used this T-harness for my 2003 Honda Accord EX-L V6 Coupe when installing iDatastart CMHCXA0 HC. Honestly, if it was not for this harness, I probably would not have installed remote start because there are so many wires to splice. With this harness, I only had to splice 6 wires. Remote start is working great.

Pros: Makes life easy

Cons: Price

Worth every penny!

The adapter harness was easy to install. After getting the covers off the steering column, it just plugged in to the OEM connectors. After that, I just had 4 connections to splice in under the dash and I was ready to go. I don't like splicing into the OEM wiring any more than absolutely necessary. Using this harness makes most of the connections needed simple and clean.

Pros: Just plug it in and go with minimal tapping into the OEM harness.

Cons: There were quite a few extra wires not needed for my installation, but I just tied them up out of the way.

Product Research


Overview: The iDatastart THR-HA2 installation harness is designed to simplify the installation of your iDatastart CMHCXA0 remote start module (sold separately) into select 2001 - up Honda and Acura vehicles with standard keys.

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.
