Although you can hardwire a stereo into this car, it's not recommended. Your car needs a class II data interface for everything to work properly. Metra makes one for your car. the model # XXXXX XXXXX (does not work with onstar). You can pick up one of these or a like model at most any install shop.

Here's a description of this part:

METRA - GMRC-01 - Metra GMRC-01 lets you install an aftermarket receiver in se


Model: GMRC-01

  • Class II data interface provides OEM integration for aftermarket radio installations in GM vehicles with Class II data systems
  • Delivers effortless integration without compromising vehicle data system. (No more relocating radios)
  • Supplies 10 amp 12-volt switched power Chime for door, headlight and key in ignition warning.

The wiring harness has a white 10-pin female connector (4 pins present) on one end and a gray 24-pin male connector (14 pins present) on the other end. The 10-pin connector plugs into the VT-GMRC-01 and the 24-pin connector interfaces with the existing factory plug.

Note: Will not work with OnStar equipped vehicles

This will work if you haven't cut off the factory harness. I highly recommend you use this part. If you decide not to, & still want the wire colors, let me know & I can provide that.
