Lets go over what this harness is, and what it does. The obvious, is that it’s an LS2 | LS3 Engine Harness. This harness uses brand new wire and brand new pins, and mostly brand new plugs. In the initial mockup and R&D process the harness was completely re-designed and re-measured to fit perfectly along the motor. No wasted length on any of the sensor looms. The harness now routes along the back of the intake manifold and each connector to its dedicated location. This makes for a great look, an easier install, an engine bay with less clutter, and much easier to work on when under the hood.

Whether it be the veins of an engine swap, an old harness replacement, or to add needed aftermarket electronics for your build...our products offer something for everyone. 

CM2 (CB-LS2-CM2) (+$300.00)

 

The CM2 Engine Harness features all the same great specs and innovation as our CM1 but adds a Circular Mil Spec connector and Raychem Shrink Boot that we’ve adopted from the aviation/military industry. The connector location varies on the harness and chassis, 90% of the time it is to be mounted to the OEM harness entry hole or former A/C hole (if A/C is eliminated). The Circular Mil Spec connector serves multiple functions. For the racers or anyone working in their engine bay its 1 second to release the harness from the chassis to do service or drop the engine. If you’re in the pits and on a time crunch this can save a considerable amount of time. Aesthetically the Mil Spec connector improves the engine bays look and appeal substantially.

CM3 (CB-LS2-CM3) (+$700.00)

The CM3 harness shares the same great specs and innovation as our CM1 & CM2. But in addition to the Circular Mil Spec connector the CM3 adds Raychem DR-25 Heat Shrink Loom and yellow sensor labels on each individual connectors loom. Raychem DR-25 is perfect for any harness near extreme heat conditions (operating temp. -103° to +347° F) This is the most durable harness money can buy. Built with high performance and full functionality in mind, the same material and assembly technique was adopted directly from the aviation, NASA, and military industry.
