Custom Wiring Harnesses

Click to Enlarge
Our LS1 and GenIII truck engine harnesses are made from high- quality TXL rated wire. Each harness is covered in high temp mesh covering for flexibility. Every terminal is crimped and soldered to avoid corrosion and contact problems.
The harness includes a fuse box, OBDII diagnostic port with SES light, GM fuel pump relay and easy 4-wire hook up.

This makes it an easy plug-n-play design.


LS2 harnesses coming soon.

Electric Fan Wiring Harnesses

Click to Enlarge
Our fan harness is direct replacement for the Flex-a-Lite VSC.
It's also available for truck owners who use the LS1/LT1 style Camaro fans and the new 2005 OEM truck fans. The fans are controlled by a set of relays that are triggered by the PCM and A/C signal. The harnesses are made from high- quality TXL rated wire. Every terminal is crimped and soldered to avoid corrosion and contact problems. Each one is covered in wire loom and comes with all parts/connectors. No need to run to the auto store for a part.
For the Flex-a-lite owners, the power wires come with a heat-shrink terminal so you will be able to attach to your existing fan wires.
For LS1/05 style fans, OEM weather-pack terminals are included. This makes it an easy plug-n-play design. A manual switch and LED's are available as options.
