This is an original factory 20-pin plug with wiring pigtails. This would be spliced into your existing harness if your factory plug has been removed from the vehicle. This was the only 20-pin plug offered by GM, so if you've counted 20 pins on your main plug, this is the one you need. This style of plug was used in:

• Buick - 1989-1994*
• Cadillac - 1989-1994*
• Chevrolet - 1989*-2002*
• GMC - 1989-2002*
• Oldsmobile - 1989-1994*
• Pontiac - 1989-2002*
• Saturn - 1989-1999*

If your vehicle is equipped with steering wheel controls, please be sure to let us know, as not all plugs have wires for those terminals.

*Not all models had this plug style in all the years listed. Please check your radio before ordering. Some of the 80s and early 90s models had a 21 pin plug. The main parts of the plug (power, ground and speakers) were the same, so you could probably make this work in a 21 pin application too.
