Yeah, I didn’t see the number before because the print was too large in the title line. Lol. Duh. Anyway, it’s weird: Yesterday, when I typed that number into Marine Engine.com, two showed up at $50 each. Today, they are gone. Yesterday’s picture showed the red plug okay but, like yours, it was coiled. You couldn’t see any more details of the ends. These trim wires….I assume they are blue and green, # 14 or #16-ish in size? Do they end inside the red plug on the engine end, or is there a separate harness for them? Everything I can remember (which is getting less and less every day) had the trim harness separate from the main harness, where they went through the lower cowl, or in the 1977-ish vintage, never even made it into the engine cowl but joined up in a junction box inside the boat.
