1978 Merc 700/70hp 3 cyl. wiring harness issue Page: 1 Re: 1978 Merc 700/70hp 3 cyl. wiring harness issue Is that an internal harness for the 1978 70hp you found? Test it very carefully with a meter for continuity between the pins and proper wire terminals, and for lack of continuity between pins. Do that while jiggling the wiring harness around a little near the connector.
