This 10-amp fuse, located near the main fuse box, is for the instrumentlamps.
Maximum Protection
The Painless Performance wiring harness is designed with your safety inmind. There's a main fuse box with separate fuse terminals positionedaround the wiring system. The main fuse box has 12 circuits. They feedand protect the following circuits for the coil, turn signals,windshield wipers, air conditioning and heater, sound system, backuplights, electric cooling fan, switched accessory, always hot lead forclock and courtesy lights, headlights, horn and cigarette lighter(always hot), and brake lights.

This is the Maxi-Fuse, which sits protected in a plastic cover at thestarter solenoid. Power through the 10-gauge red wire comes from thebattery's positive cable at the starter solenoid. Power enters the mainwiring harness here. Removing or blowing this fuse completely disablesyour Mustang's electrical system.
Separate fuse terminals, located away from the main fuse box, protectspecific areas of the electrical system. For example, there's a 10-ampinstrument lamp fuse located near the main fuse box.
The Maxi-Fuse, located near the starter solenoid, protects the entirePainless Performance electrical system because it stands between batterypower and the main wiring harness under the dashboard. When the 50-ampMaxi-Fuse blows, all electrical power from the battery is cut off. Thinkof the Maxi-Fuse as double protection, meaning there are two fuses forevery circuit. Each circuit has a primary fuse at the main fuse boxunder the dashboard. The secondary Maxi-Fuse provides a comfortableredundancy against short circuits and fire. This feature would come inhandy should a short circuit develop between the battery and main wiringharness.
Don't Be Rubbed The Wrong Way...
One of the biggest mistakes we see in our travels is vulnerable wiring.A wire's insulation isn't enough protection against chafing, whichhappens when wires rub against hard surfaces. When bare wires touchsteel surfaces, nasty short circuits can develop, potentially causing blown fuses or even fires. Your best path to protection is plenty ofprotection around the wiring. Use rubber grommets where wiring passesthrough steel bulkheads, and wrap your wiring in that ribbed plasticanti-chaf. These two practices, plus the use of heat-shrink, will keepyour electrical system safe.
