The cam sync plug installs in place of a traditional distributor, providing a hall-effect cam sync signal needed for the EFI system to reference the # 1 cylinder. MSD's cam sync is a plug and play with Holley EFI systems and can easily interface with most aftermarket EFI systems. The cam sync plug will have 2-3/4" of adjustment.
