This modern fuse panel replaces your shorted out, burned, or non-functioning original fuse panel. It restores original electrical performance & predicted reliability. And, it's ideal when upgrading your car with all-new wiring harnesses and/or adding aftermarket radios and amplifiers, fuel injection, dual electric cooling fans, 1-wire high output alternators, cruise control, alarms, power antennas, power windows, power door locks, or power trunk locks
