Overview

The Racetronix FPWH-001 is a fuel pump wiring harness designed for 1998-2003 GM SUVs with the Delphi 150-Series 4-position square connector. This harness provides a direct connection from the alternator to the fuel pump, bypassing the factory circuits. It features 10-gauge copper wire, a heavy-duty relay and fuse holder, and includes necessary hardware like silicon grease, a spare fuse, and wire ties.
Show original supplier description
The Racetronix FPWH-001 fuel pump wiring harness is engineered to deliver maximum performance from high-performance fuel pumps by providing a dedicated, high-capacity power source. Constructed with a 10-gauge stranded copper main lead, the FPWH-001 minimizes resistive power loss. It includes weatherproof, factory-quality connectors, a heavy-duty weatherproof relay and fuse holder, and a redundant ground upgrade with battery nuts. Installation is plug-and-play, requiring no cutting or splicing of the factory wiring. The kit also comes with silicon grease, a spare fuse, and wire ties. It is critical to audit your vehicle's chassis connector type before ordering. This harness is specifically designed for vehicles still utilizing the original GM Metri-Pack 150-Series (4-position square) connector. If your vehicle has been converted to the upgraded Metri-Pack 280-Series (4-position flat) connector, you will require the FPWH-023 harness. Additionally, the FPWH-001 is no longer recommended for 1999-2002 F-Body Camaro/Firebird models; the FPWK-017W is the recommended alternative for those applications. The Racetronix FPWH-001 also includes an interface connector for the optional Plug & Play addition of a pump booster or voltage amplifier, such as MSD or KB units, via their PBIC connector set. For enhanced grounding, the BGK8 (Battery Ground Kit) is highly recommended.
