The bespoke harnesses are individually built to your design to give a perfect fit for your engine bay. You do not need to design a complete wiring harness though, just download the simple design form, measure a few lengths, and we’ll do the rest.

The perfect harness must also fit perfectly

Built in-house 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.

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.

High grade materials

for high performance and a long service life

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.

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.

Each connector leg is labelled for quick fitment and the label is covered in clear heatshrink protecting the text from abrasion, oil and solvents so you can always read it.

The twisted cables are incredibly flexible, allowing tight turns without stressing any of the materials.

Easy fitting

Through good materials and detailed design

Race specification harnesses are built in-house by Omex engineers ensuring the attention to detail is the same as we expect of all our products, regardless of cost. Quality control checks borrowed from the aerospace industry, then modified to suit our harnesses, ensure that every harness is checked by two engineers to prescribed standards.

The ‘Basic’ design covers everything needed for most N/A engines. ‘Basic plus MAP’ adds a MAP sensor connector for use with forced induction engines. If you want extra features such as full throttle gearshift, launch control etc Omex can add these for you, or an auxiliary wire pack can be added to give you all the extra cables for auxiliary functions to wire in yourself.
