.After a repowering with a new four stoke fuel gauges not working. The Merc mechanic put a new wire harness to the back of the motor and the old 14 pin harness was also hooked up there was two harnesses he said won’t be needed. I’m suspecting one went to the oil and there as a six pin not being used. I’m wondering if this one is the one needed for the fuel gauge. Any help would be appreciated
