This harness is designed for Chevy LS and late-model truck engines that have a 58-tooth crank sensor and a four-pulse cam sensor. In most cases, that includes LS2, LS3, LS7 and truck engines 2007 and later. You can normally identify which crank sensor you have by observing the connector on the engine block. A black connector indicates a 24-tooth wheel, but a gray indicator indicates a 58-tooth wheel. If you have the 24-tooth version you will want to opt for the LS1/LS6 harness instead.
