Are you changing your engine setup from a 24x to a 58x, or putting an LS2 in place of an earlier LS? This adapter will connect directly to your rear 24x Cam Sensor Connector, and plug directly into your front Cam Sensor in the timing cover. Pinouts are correct for each end, meaning you don't have to swap any wires to get it to work. Fully shielded for maximum protection against interference and electrical noise, and loomed in braided split-loom for that integrated look. 30" long. Works perfect for all Holley applications, such as Holley Terminator X, Terminator X Max, HP, and Dominator.
