CM2 (CB-2JZ-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-2JZ-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.
