My Merc 850 Thunderbolt is 4 Cyl, 1973 or 1974, Serial #3877880.
The original Internal wiring harness is part # 8466055, this unit has 6 male post in it.
The CDI electronics replacement part is 414-2770, this part has 7 male posts in it.
When that extra 7th post plugs into my external wires with 7 females, oem part #45876.
What should I expect? I currently do not have the seventh post, only 6, but the external side will accept the seventh on the new CDI part?
Any help or past experiences with this will assist greatly.
