Description
Are you wanting to fully rewire your Holley EFI installation? Or perhaps you are starting a new build, and want to wire everything perfect the first time. Introducing two new items from Holley EFI that will help you accomplish your goal. The unterminated main harness comes with both J1A and J1B connectors full terminated with 15′ of flying lead wiring. If you already have your own wire and simply need the connectors and pins, we have you covered with our new ECU connector and pins kit, allowing you to fully terminate your own custom main harnesses! Check out this part and all of our other great Holley EFI Wiring Shop items, such as sensor connectors, 3 and 7 wire cable and much more!
