I have a 1967 Gs400 convertible that I am in the process of rewiring.. Im having trouble with the accessory switch and the power top.. How do you connect the wiring... the switch has three posts all of which run parellel to each other two on on row the a little farther down a single.. the wiring going to the power top motor has two blades. and they are perpendicular to each other... the color of the wire to the motor is purple and a grey.. HELP PLEASE... What am I doing wrong. and the wiring diagrams I'm finding dont show the power top option
