Need to know what wires do what on 7 prong plug. Found diagram but it only tells code no. Found 68 with what color does what. After installing a new plug to get dash lights I ended up with no turn no high beam and still no dash lights. I know my wife said I am too old.

yellow or yellow with a white stripe are bigger dia. and are generally the power supply. blue with a red stripe will be the dash lights... if that helps?
