We offer an LSx, non-emissions, show quality engine harness that can be custom designed to your exact needs. Extra effort is made to ensure the harness layout comfortably fits the engine while maintaining an exact fit.

All harnesses are built with new, OEM connectors, terminals and seals. Every crimp is performed with approved tooling.
This ensures 100% continuity throughout the entire engine harness.

Every harness has a fuse block incorporated, ignition relay, fuel pump relay, data link connector with an LED SES light and our easy 4-wire hookup.

All wiring is TXL heat rated (250°F) which has a thin coating to reduce the size of the harness thickness.
This allows for easier bending and routing, which gives a clean look.

The harness is then covered with a black nylon mesh that protects the wires from abrasion and gives the harness a professional look.

Before the engine harness is shipped to the customer, it is thoroughly tested by verifying each pin and terminal pinout. The harness is installed on our engine test stand to verify functionality and operation.
We go a step further to ensure our customer is never faced with a harness issue by verifying every component is functioning while the engine is running with our diagnostic tool.
A multi-point check list ensures each sensor is verified.

When the customer receives the harness and installs it, they can rest assure that their conversion will start up the first time!

In addition to engine harnesses, we also offer PCM/ECM programming, fan control harnesses and misc wiring solutions.
