Overview: The iDatastart ADS-AHR-HCX  "Splice" wiring kit lets you do a hardwire installation of an iDatastart CMHCXA0 remote start module (sold separately) into most any year/model vehicle from 1988 - 2021. Installation wiring harnesses are provided that plug into the CMHCXA0 remote start module and have bare-ended wires for splicing into the vehicle's wiring. Main connections include Power & Ground, Starter, Ignition, and Accessory Power. Other connections include Parking Light Flash, Door Locks, as well as Door, Hood, and Truck pin switch connections (individual functions will vary, please see vehicle specific information for details).

Note: The iDatastart ADS-AHR-HCX remote-start hardwire kit will require extensive splicing into the vehicle's wiring for installation.

Customer Q&A

3 questions already asked

Does it use your existing remote, or is there one specific for this?

Greetings Jeff, and thank you for your question. This is a hardwire kit, not the actual remote start module. You will need this as well: In a lot of cases we will have a vehicle specific, mostly plug and play T harness. If the vehicle does not have such a T harness, then you would use this hardwire kit. Most cases can use the factory key fob with the CMHCXA0 module. We would need more specific vehicle information.

Does this fit a 2023 legacy sport? The only option is a sedan, which it is, but the sport is a little different.
