You can also try to buy an oem wiring kit for your make and model vehicle. You just splice in the connector to your new radio and plugs into your factory connector. You can look online like Best Buy or some where that installs radios.

Hello, I'm Danny.

I've attached three pictures of the stereo wiring diagrams. Here is a tutorial showing how to check wiring:

The picture #1 is early production with amplifier, #2 is late production with amplifier, and #3 is radio without amplifier. Hope this helps and thanks for using 2CarPros.
