I purchased a module it came off a 2000 350 carb engine but it has no wiring harness. This module is stacked the top is the knock the bottom is the ignition timing curve it has two sets of plugs . If anyone has a harness or has a wiring diagram it would be very helpful. The only other route is to get the older version timing module but which one is a better unit? Thanks for any help Jeff
