Install a New Car Stereo

By Matthew Wright, About.com Guide

Don't screw the new stereo into the bracket just yet. It's time to start the wiring process. Since you were smart (weren't you?!) and purchased the wiring adapter with your car stereo, all you have to do is connect the new stereo's wiring harness to the adapter, and it's plug-and-play.

To connect the stereo's harness to your adapter, you'll need to strip the wires and crimp the connections. Never install a new car stereo using only electrical tape or those twist-on type connectors used in house wiring. These aren't acceptable or safe ways to keep automotive wiring in place.
