AEM's high-quality, color-coded master wiring harnesses include everything you need to properly wire your racecar in one easy-to-follow configuration (sold separately). We silk-screen each individual wire function onto the body of the wire to ease the installation process and reduce any chance of misidentifying a wire during set-up.

AEM's 72" master wiring harness includes built-in fuses and relays for fans, pumps, auxiliary power, and more. AEM also has a 24" wiring harness for adapting our Universal EMS system to an exiting wiring race car harness, and harness mating connector kit with 104 contacts.
