We will not be held responsible if a customer fails to acquire all the components to complete this kit. READ BELOW!!!

* This harness reconfigures the factory wiring to supply dual positive feeds and redundant grounds to the fuel pump. This is required in order to handle the high current demands of our FPA-055-255E, FPA-055-340E and FPA-055-450E pump assemblies. It cannot be used with the factory in-tank harness. This harness requires the use of our BCA-4W bulkhead connector and our ITWH-052 or ITWH-054 in-tank harnesses show under add-ons below. It may also be purchased as a kit under FPWK-052 or FPWK-052-D under related items below.

Alternator-direct power for maximum voltage / True PnP with GM type connectors:

The Racetronix PnP upgrade harness provides alternator direct power for maximum pump voltage. Racetronix has documented an
average 1.2-1.5V increase in pump voltage in the C5 which equates to a 15-18% increase in pump volume based on Walbro's
specifications and Racetronix field tests. A minor increase in fuel pressure will actually be experienced with the installation of this
harness. The harness is fully 'plug and play' and is installed without cutting into factory wiring. The entire harness is weatherproof
made with the same Delphi interconnect components used throughout your C5. The harness' operation is quite simple. The factory
power wire which was once used to power the fuel pump is used to trigger a relay which in turn supplies
power directly from the alternator with fused protection.

Redundant grounds = improved voltage & reliability:

A redundant ground is provided which loops into the harness. This loop enhances ground to the factory harness making a two-fold
improvement. A secondary ground for the fuel module is also provided. This enhances the ground at the pump's source and through the fuel module's body. (see above)

Pump-booster PnP ready:

The Racetronix harness is equipped with an intermediate high-current (30 amp) connector just after the relay. This allows for easy
plug & play addition of a pump voltage booster which can increase pump performance upwards of 30%. A spare connector
assembly set is included so that any booster can be adapted to plug into the Racetronix harness. The Racetronix harness further
enhances pump booster performance by eliminating voltage drop. The heavy-gauge power feed is more than capable of
handling the 15-20 amp loads generated by the pump at boosted voltages.

Hardware included:

There is nothing worse than being in the middle of an installation only to find that the manufacturer has skimped on installation hardware. This is why Racetronix supplies a spare ATC fuse, 25 black nylon wire ties, silicon grease and stainless mounting hardware with each kit.

Racetronix harnesses are considered the best by which all others are judged. Attention to detail in every Racetronix harness is evident at first glance. Racetronix spares no expense to ensure reliability, ease of installation and performance.
All Racetronix harnesses are assembled using our computerized crimp-quality monitoring system and then circuit checked for the utmost in reliability. This Racetronix harness is backed by our limited lifetime warranty.
