SOURCE: installing after market stereo
You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!

There is an updated resistor/connector package. Very expensive from GM, try your local NAPA or other parts supplier for a replacement

Theres a standard amongst most stereos, so if these colors apply, then you will be right,
Red is Ignition power
orange is direct power
Black is earth
blue is for phone
White is for electric arial
then there will be four coloured wires with matching color trace wires, these are the speaker wires.
Hope this gets you going, good luck.
