The Wiring Harness aka 'Hotwire harness'
No cutting, splicing, crimping or soldering. Retain factory configuration. Just plug it in and you are done!
High performance fuel pumps need a good power source in order to perform to their full potential. On average a Walbro high-performance fuel pump requires twice as much power as a factory fuel pump. Factory wiring is just enough for a factory pumps power requirements because manufacturers need to save cost and weight. Racetronix field tests have shown that running a high-performance fuel pump off of the factory wiring can cut pump performance by 30% or more. Problems with failing factory relays, connectors/terminals and fuse contacts are also common when excessive load is placed on them.
This Racetronix plug and play harness is designed to remove all fuel pump load from the factory pump circuits while providing the pumps with a new heavy-duty power source. This Racetronix harness gets its power directly from the alternator's battery terminal. The voltage at the alternators output is typically 1-2 volts higher than at the battery when the motor is running (high charge/load conditions and WOT). This means that your high-performance pumps can provide as much as 20% more fuel in some cases. This Racetronix harness uses high-quality automotive-grade wire which is resistant to oil, gas, heat and rot. The extra thick length of wire in this Racetronix harness helps reduce resistive power loss to almost non-existent levels. This helps improve pump performance by as much as another 10-20%. High-quality weatherproof fuse holders and relays are used for maximum reliability. The Racetronix harness has factory-type weatherproof connectors which plug directly into your fuel pump module/sender so no cutting or splicing is required.
REDUNDANT GROUNDING SYSTEM:
The Racetronix harness has a redundant ground upgrade as it is necessary to improve the pump's ground (-) supply as well. All grounds (including the factory) are routed back to a common piercing ring terminal which provides direct ground from the large tank strap bolt and body. This provides superior clamping force and grounding. A WeatherPack terminal removal tool is supplied so that the factory sender ground can be re-used / interfaced with this Racetronix harness which provides another redundant ground. The weatherproof relays share these mounting locations so that no mounting holes must be drilled. Silicon grease is provided to coat the relay brackets and grounding ring terminal in order to prevent corrosion.
Harnesses made by other companies do not have this unique feature but rather they require you to drill / tap holes in your car to attach a separate ground strap and mount your relay. To make matters worse they loop the factory ground in and out of the power feed connector to save the expense of running a dedicated wire. Running two wires into one seal does not allow it to seal properly so moisture could get in and corrode both the factory sender connector and upgrade harness.
The Racetronix harness is covered with Nylon loom (GM spec. GMP.PA6.003, -40ºF to 300ºF). Nylon loom is more flexible, slicker, shinier and has a higher temperature rating than the PE loom used by other vendors. Nylon loom provides superior protection and eases installation especially in colder climates.
Our power feed comes off the back of the alternator where voltage is highest. It then runs through a weatherproof fuse holders which are mounted on the back of the alternator with a supplied stainless steel bolt. The TR has an unused hole in the back of the alternator which facilitates this fuse holder mounting quite nicely. This location keeps the fuse holder out of sight and the unfused wire down to a short 4 inches. Our competition's fuse holder must be remote-mounted requiring self tapping screws / holes. The unfused section of wire extends to the firewall.
Racetronix supplies spare 20A ATC fuses, numerous black vinyl 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.
Some people make the mistake of assuming the thick black wire coming from the battery is a body ground. It is not. It is the motor ground and the motor sits on rubber mounts. Due to the age of the TRs we have seen some body grounds so bad that the lights flicker on the car when in motion. To address this problem Racetronix is offering a battery to body ground upgrade kit. This kit upgrades the thin ground wire running from the battery to the inner side of the passenger's fender wall. It includes an 8 gauge copper wire fitted with terminals and battery nuts with accessory taps.. One end attaches to BATTERY - and the other to BODY GROUND. No modifications to the factory battery terminals or boots are required. The new battery nuts have a bolt on top that allows connections to easily be made to the battery. Simply pop the old factory battery nuts out by pushing them out from behind and pop the new ones in. They even look good too. > BLING :) <
