I have a 1969 Evinrude 55hp with a WABASH amplifier. I am not sure it is wired correctly. Can anyone please help me. The amplifier is part # 389549. It has a purple, grey, black & white, and blue wire. Do the purple and grey go to 12volt + and the black white to the points and the blue to the coil?
Thank you for your help
