CRUX Wiring Harness

The Crux GM49R-EXT is a 5' extension harness that is used in conjunction with Crux's CS-GM43 radio replacement interface module (sold separately) for select 2019-up GM vehicles where the factory radio control module is located at the front passenger side (by the door hinge). The GM49R-EXT can only be used with GM vehicles that have a factory IOR code radio installed (not compatible with IOS, IOT, or IOU code factory radios). The radio code can be found in the vehicle's glove box. Please contact an Advisor at 1-888-955-6000 to see if the GM49R-EXT harness is compatible with your vehicle. Warranty: 1 year.
