Not sure how to wire them, but I have an idea.

I am curious; why no variable speed?

I have been using it with the variable speeds and it does not really do anything for me. It is pretty slow on max speed, any slower and I may as well just swim!!!

Plus due to the rudder loaction the boat does not handle well at slow speeds with the motor powering it. It will turn very tight with the pedal powered prop, so that is how I get it up to my dock.

I do have all of the electronics that came with the broken trolling setup, which includes a variable speed setup and on/off switch. I may just take that apart and adapt it. Not sure how easy that will be...

I guess I can look into a pair of stdp relays, I liked the potted sealed one I linked to, and found it for about 50 bucks shipped.
