PRODUCT DETAILS
The Rywire Mil-Spec Fuse/Relay Box Sub-Harness is an essential upgrade for racing enthusiasts and engine swappers. Available in two options—Honda K Series Engine specific and a universal version compatible with a wide range of swaps including Honda B, D, and H Series—this harness simplifies and optimizes your setup for maximum efficiency and performance.
K Series Specific:
The K Series harness is perfect for race cars running solely the engine. This harness features five relays and fuses, facilitating the operation of Rywire harnesses or OEM 02-04 RSX/EP3 harnesses in any car. It includes flying lead connectors for the fan and fuel pump wires and a flying lead harness for optional gauge cluster functions. Key components include a COMPUTER, FAN, FUEL, STARTER, and O2 SENSOR RELAYS, a COMPUTER "E" plug prewired, a C101 plug-and-play engine harness connector, a primary 4-wire O2 sensor plug, an easy hookups to cluster wiring, and ignition switch. It is designed to work with factory-style K series harnesses like "K2-base" or "K2-Milspec" but is not compatible with the Infinity K harness.
Universal Version:
The universal race fuse/relay box offers a versatile solution for various engine swaps. It includes 5 relays and fuses, a 4-pin DTP connector for the fuel pump, fan, spare output, and switched output. This harness was designed for Rywire B/D/H series harnesses but can be adjusted to integrate with other engine harnesses upon request. Installation is straightforward—just run wires to the fan, fuel pump, power, and ignition switch, and you're ready to go. This product works seamlessly with a switch panel system and includes an auxiliary relay for electric water pumps, lighting, and other accessories.
Both versions of the Rywire Mil-Spec Fuse/Relay Box Sub-Harness are built using top-quality materials for reliability and performance, making them an ideal choice for any race or high-performance vehicle setup.
You may need a Mating Deutsch Connector if you use this fuse box with a switch panel different from the Rywire Switch Panel.
