Omex 600 Basic Race Spec Loom


Built by Omex engineers using some of the same materials as found in race series all the way up to F1



Lightweight, thin wall automotive grade cable is used throughout, designed to withstand the oil, solvents and temperatures found in engine bays.

Gold plated terminals are used at the ECU as it is the lowest resistance material for contacts, giving the best signals to the ECU from the sensors.

The cables are twisted together to reject radiated electrical interference from sources such as the high tension sparks, alternator and starter motor, meaning the signals from your sensors are still good when they reach the ECU. Many harness manufacturers tightly machine-twist the cables together as this is the fastest method but one which causes unwanted stresses in the materials. Omex harnesses are twisted by hand so they don’t just look good, they are mechanically perfect.

Covering the cables is motorsport-grade heatshrink for the correct solvent, heat and abrasion resistance for racing engine bay use.

Joints and connector backs are covered with glue lined heatshrink which is stiff to reduce stresses from the harness bending at these joints. It also minimises tension on the wire joints, moving these tensions to the strong connector housings and cables.

A relay for managing power to the injectors, ignition coils etc is fitted to the harness as standard. There is also wiring to allow ECU control of a fuel pump relay and radiator fan relay already on your chassis harness, or optionally Omex can add these relays to your ECU harness.
