Connect the SOGCM-18 to your aftermarket radio, mount the module in a location where the chime can be heard, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. You'll also keep your vehicle's factory front and rear parking sensors.

Retained Features: The Crux SOCGM-18 retains your GM vehicle's factory amplifier, parking sensors, R.A.P. (retained accessory power), and warning chimes.

  • Factory Amplifier: The SOCGM-18 will retain your GM vehicle's factory installed amplifier. It supports factory equipped Bose, non-Bose, and Y-91 audio systems. Balance and Fader controls are also retained.
  • Parking Sensors: The Crux SOCGM-18 retains your GM vehicle's factory front and rear parking sensors (it does not retain backup camera).
  • Retained Accessory Power (R.A.P.):  The ignition power source of most GM vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The SOCGM-18 is designed to retain this feature.
  • Warning Chimes: The Crux SOGCM-18 retains factory warning chimes through the use of an on-board speaker. It also offers adjsutable chime volume.

Notes:

  • This interface will not retain OnStar.
  • This interface will not retain steering wheel controls.

Outputs: The Crux SOCGM-18 is outfitted with 12V/4A Accessory, Illumination, Amp Turn-On, and Reverse Gear outputs.

  • 12V/4A Accessory Output: In many GM vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The SOCGM-18 is designed to provide a 12V/4A switched accessory output (red wire).
  • Illumination Output: The Crux SOCGM-18 also offers an Illumination output wire.
  • Amp Turn-On: In addition, the Crux interface provides an Amp Turn-On lead.
  • Reverse Wire Output: The Crux SOCGM-18 includes a Reverse wire output to make the installation of an aftermarket navigation or multimedia receiver easier.

Note: The interface does not provide a Parking Brake or VSS wire output.

Will this harness work with my steering wheel controls as well? 2008 Cadillac Devill DTS

Greetings Austin. Thank you for your question. No sir. This harness does not have the steering wheel control module needed to translate code. We do have other options. Please contact an advisor here at 800-324-9695 for the best option.

The SOCGM-18 is not capable of retaining steering wheel controls. You'll need an additional steering wheel control interface. For your vehicle, the Axxess ASWC-1 would work with the SOCGM-18 in order to retain steering wheel controls.

What is the micro-b usb for on the harness? Iâ??ve got a 2012 Silverado 1500.

That is a great question, William. That port is used to connect to a PC in case you need to update the firmware on the unit. For most installs, the micro-b USB is never used. I hope this helps!

Greetings Mario, and thank you for your question. I see no reason that it would not work. Please contact one of our advisors at 800-324-9695 with your vehicle information to see if this would be the correct harness for your vehicle.

Q
Every once and a while my radio will not work and none of my chimes work. If I unplug the radio wires from this and plug it back in it works for a couple weeks and then nothing works again. What would cause this?
