Looking for a techmate pro for the year 2000 port

I have a brand new Techmate pro scan tools. Plus which ever harness adaptors you need for all marine ecms. Most adaptors are 49 bucks but not all, it just depends on which engines one is going to scan. You need to scan a 2000 year model engine ? These diacom scan tools are the latest updated versions and Mercruiser G3 scan capabilities.
