FPWH-008HD - 2003.5-2013 C5/6 Fuel Pump Power Upgrade (Hotwire) Harness

New 2025 HD version

ELIMINATE FUSE CENTER DAMAGE: Performance pumps far exceed the factory circuit's power handling capability. This harness provides alternator-direct power, eliminating the possibility of the factory relay or fuse center being damaged/melted. It typically provides a 10-20% increase in pump volume.
  • Plug & Play (no cutting or splicing) with weatherproof factory connectors.
  • Heavy 10 gauge automotive-grade copper wire.
  • Heavy-duty 40 amp 630-series weatherproof relay and ATC fuse holder.
  • Redundant grounds for improved voltage & reliability.
  • Pump Booster Ready: Equipped with an interface connector for easy PnP addition of KB BAP or MSD boosters via optional PBIC connector.
  • Includes: Silicon grease, spare fuse, wire ties, and stainless mounting hardware.

IPH-008 - C5/6 Intermediate Pump Harness

PREVENT CONNECTOR MELTING: The factory intermediate harness is three gauges smaller than the Racetronix 10-gauge upgrade. This undersized factory wiring is a primary cause of connector failure and severe voltage loss. The IPH-008 is mandatory to maximize flow and ensure reliability.
  • Upgrades wiring from the driver's side wheel well to the connector on the fuel module at the top of the tank.
  • Heavy 10 gauge automotive-grade copper wire.
  • Weatherproof factory connectors.
  • Essential for 340LPH to 450LPH+ pump upgrades.
SYSTEM CONNECTION FLOW:

ALTERNATOR ? FPWH-008HD (Hotwire) ? IPH-008 (Intermediate) ? FUEL MODULE

NOTE: Access to this area (dropping the tank) is required to install the IPH-008 intermediate pump harness.
