1974 Evinrude 25hp Cable?

[MMcCawley]

Hi,
My father gave me a 1974 25 hp Evinrude 25402M that I'm trying to get running. The motor has a 4 or 5 prong connector that I'm ***uming is used to remotely control the throttle. Can anyone confirm this or provide more insight as to the purpose of this connector? Also, would you happen to know the part number of the corresponding cable and where I may be able to purchase one?
Thanks for your help,
Matt
