-11% Auxiliary Harness, J1A/B Connector Inputs/Outputs

On all Holley main harnesses (with the exception of the Terminator main harness) there is an 8-pin Metripak connector that provides access to four configurable inputs and four configurable outputs. This auxiliary harness lets you create a custom sub-harness that will plug directly into that 8-pin metripak. Use this for nearly any sort of remote switch or to control any electronic output, including 12-volt switched, ground-switched, and positive or negative PWM controls.
