The following is a load of wiring I have had written down for ages for our cars. Also some of it is gathered from working on other CL's. This information is provided AS IS and I am NOT responsible if you burn down your car. ALWAYS test all wiring with a digital multimeter before making ANY sort of connection to your factory wiring.

Wire colors will be listed as SOLID/STRIPE COLOR followed by polarity. If no polarity is listed, it is generally positive.

Power Window Motor Wire Colors
Window motors swap power / ground over the two wires given to either make the windows go up or down. If you supply only 12v to one side and not ground to the other, nothing will happen.

If you supply 12v to the Up wire and ground to the down wire, the window will go up, and the same goes for putting the window down.

Driver Up/Down: Red/Yellow and Red/Blue @ Switch in driver door
Passenger Up/Down: Blue/Yellow and Blue In driver kick panel

Great info, even greater disclaimer

 

Yeah, should be helpful for just about any electrical DIY project. Priceless if someone wants to install their own alarm or remote starter.

 

I have this car and I'm changing out the audio unit and this diagram isn't right at all
