I have searched and haven't found anyone who has done something quite like I am planning. I have included a picture below of the wiring I have thought out so far. I plan to use a DCController Fk35 to operate the low speed portion of the Taurus fan, and have a SPDT switch that will allow me to disable the FK35 and activate a 85A relay to run the High speed of the fan when I choose. I will also be able to disable the fan entirely for water crossings.
The problem I am running into is how to disable the FK35. Can I just hook up the IGN source from the switch to the IGN line of the FK35?
