WIRING LOOMS

Race Spec has established a trusted reputation of producing motorsport wiring looms of the highest quality for various markets.
Each race wiring harness is custom-built to order for the particular project in an effort to maintain our unrelenting commitment to quality. Starting with a thorough consultation, the required information and details are gathered so the initial design and documentation process may begin. Connector selection, material options, expansion provisions, and custom wiring loom requests are carefully addressed so the finest product can be produced; one that will withstand the continuous abuse that race days are known for but more importantly one that may assist in propelling you to the winner's circle.
Raychem System 25 material, Deutsch Autosport interconnect solutions, MIL-Spec wire and cable, and a large selection of genuine mating connectors are inventoried and carefully selected.

      DO YOU NEED MY ENGINE/VEHICLE TO BEGIN AN ORDER

      • Surprisingly, no! In addition to the various engines and chassis we have worked with, we can take on any type of request. We have successfully provided complete race wiring harness packages for many clients with various engine and chassis combinations without ever touching the vehicle. An additional step in our consultation process will enable us to work closely as we create a bespoke solution for your project.

      DO YOU OFFER OEM REPLACEMENT OR 'SWAP' ENGINE HARNESSES

      • We do not, our primary focus is on producing custom tailored products. It is not sensible to construct a fluid resistant loom that terminates with unsealed connectors as commonly found with OEM ECU's.
