I am trying to determine the OEM part # for the internal and external wire harness on my 1971 800 (80 HP) Mercury. But because of the age I am having trouble finding this information. The website that has the replacement harnesses has the OEM part numbers listed that it will replace.

If you look on the harness plugin there should be a 5 digit number thats the part number
