Harnesses

Just about any motorsports enthusiast gets excited about adding customized fuel injection to a high performance engine. Until they start thinking about harnesses. Oh yeah, those things. Immediately they start conjuring up nightmares of millions of feet of brightly colored wire spread all over the shop floor. Tiny pins that require precise crimping and tend to get lost forever. And don't even mention soldering.

What sets Holley Fuel Injection Kits apart is their commitment to providing easy-to-use, customized harnesses. Oh sure, a couple of crimp connectors are going to be unavoidable. But in most cases, Holley's Fuel Injection Kits come with pre-terminated connectors that allow you to make the majority of the connections with a snap of a connector.

This page shows you the various Harnesses available from Holley. If you are buying one of Holley's Fuel Injection Kits, you likely don't need to ever buy any of these harnesses. They are already included in the kit. But if you're going to assemble a custom fuel injection kit, Holley offers these various harnesses individually, preterminated for a broad number of specific applications. Choose from the following:

• ECU Power Harness: Power and ground for any Holley ECU

• Main Harnesses: Transfers all sensor, injector, ignition, and other data from the ECU to the engine compartment

• Injection Harnesses: Carries injector signals from the main harness to the injectors

• Ignition Harnesses: Carries ignition signals between the main harness and the ignition components

• Auxilliary Harnesses: All types of other specialized harnesses
