Most of the power supply circuits in these Japanese coupes are protected by fuses. High-current consumers—such as headlights, cooling fan motors, and the fuel pump—are connected via relays. The protective elements are installed in fuse boxes located in the engine compartment and the passenger compartment.
Applies to Honda Integra and Acura RSX models produced from 2001 to 2007 equipped with the K20A (2.0 L) engine.
