I have a 1963 Sea Horse Electramatic 75 HP I just got and need to know where the wires comming from the motor hook up. I don't have the harness comming from the key switch ect. to the motor. The wires comming from the motor are green and blue on the small plug, i'm guessing that's for the electric shift. The big plug has the following, yellow and yellow with blue stripe both 10-12 guage,blue,grey going to coil,white or tan going to distributor, light brown going to head,and red. The model # V4AL15E, Ser.# 2364093. I'm going to order a manual the first of the week but would like to try and turn it over to check for spark. Thanks for any help.
