J2B Auxiliary Harness Kit

The J2B Auxiliary Harness Kit from HOLLEY is designed for automotive enthusiasts and professional installers who are upgrading fuel injection systems and auxiliary accessories in performance vehicles. This harness simplifies the wiring process, allowing for a clean and organized connection of multiple auxiliary devices without the need for a complete rewiring of the existing loom.

Constructed to meet OEM standards, the J2B harness features robust wiring and sealed connectors that can endure the harsh conditions under the hood, including vibration, temperature extremes, and moisture. The pre-terminated connectors eliminate the need for crimping tools, ensuring reliable connections that are crucial for maintaining low voltage drop in auxiliary circuits. Additionally, the harness includes strain relief at connection points to prevent wear and tear.

This kit is particularly beneficial for those integrating standalone ECUs, fuel pump controllers, or nitrous management systems. It is compatible with Holley ECU systems, making it an excellent choice for builders looking to enhance their vehicle's performance. Installation time may vary based on individual experience and familiarity with automotive wiring.
