UPDATE: For customers looking for a complete harness solution for your Holley system, we now offer complete packages specifically designed for your ECU. For more details, please inquire by emailing or calling one of our sales associates.
Modern Racing Wiring Solutions is proud to offer a premium replacement for the bulky factory ECU main harness. Built with Mil-spec Tefzel wire this harness is assembled stronger and more durable than standard harnesses, offering greater heat and abrasion resistance. Designed to work with Holley HP, Terminator, Terminator X, and Dominator systems this unit is a must have for customers who are looking for a clean and easy install. Our harnesses are offered in both 10' and 15' base lengths, with a 15' shielded wire on all sizes (Ideal for driveshaft speed). We've even taken it a step further, by giving you the option of adding in pre-assembled splices to help take away the frustrating labor and headaches normally associated with wiring. Add in the fact that our harness is over 25% lighter than the factory unit and you'll find upgrading to our Mil-spec harness is a no brainer.
NOTE: Please allow up to 7 business days for all 15' harnesses, as all 15' harnesses are build-to-order.
