I got a 90 Johnson Extra long shaft I bought with about a foot of wires coming out the front of the motor. Starter button is gone that was in the under side on the corner. I would like to add a 12 ft wire cable so I can start the motor from the front of the boat with a key switch, don't know if this can be done or how to wire it. 6 wires coming out the front and when I touch the red and black to 12 volt motor wants to start. So this leaves 4 wires to go somewhere. Help is appreciated. Nowhere inside motor is room for solenoid, i want to keep installation clean
