The electrical system is a complex but essential part of what keeps your car starting, running, charging and doing the little, but important, things like locking the doors. And while voltage in automotive systems is much lower than say, household applications, it’s still important to enlist the guidance of a professional when making a diagnosis or beginning repairs because many components are extremely sensitive and can be easily damaged without proper training and knowledge.

Once you have your fuse tap, the only tools you really need to connect the car radio to the fuse box are a wire crimper tool and a utility knife. If you are installing the radio in a classic vehicle, you'll need a Phillips screwdriver to connect the wire from the radio to the fuse box. Of course, you will also need a fuse rated with an amperage value rated for your car radio. You should be able to find the recommended amperage rating for the fuse in the radio installation guide. Most low-powered radios can use a 20-amp fuse without any issues. However, for high-powered stereos, those that produce 100 watts of power or more. You may have to use a 25- or 30-amp fuse. You may be able to use a wire clasp or harness already under the dash to secure the wiring from the radio to the fuse box. If there is no available clasp or harness, though, you can use some ordinary electrical tape to secure the new power wire for the radio to an existing wire bundles beneath the dashboard. The only other items you might need are a piece of 12-gauge electrical wire and a butt connector if the power wire from the radio is too short to reach the fuse box.

Choose a spot on or near the firewall for the common ground point for the harness, and one point for a chassis ground on the negative side of the vehicle. This method gives you a single path to the negative side of the vehicle and provides a more effective ground. Use 10 gauge or bigger wire to connect the common ground to your chassis ground.

Since harnesses come in all sizes from small and simple, to large and complex, the cost to purchase and install them covers a very broad range. Some vehicle manufacturers also specify harness replacement, rather than wire repair, on certain sensitive safety systems such as airbags. This type of specific guidance varies between manufacturers and can be found in their service information.
