I could use some electrical advice. I'm putting a blower with a switch underneath my seat to help control engine heat. I'd like to tie into a positive and neutral wire that's connected to the switch that allows no power to my blower unless the engines running. Does anybody have an idea what wires I should tie into coming off of the electrical near the battery that would do this. I want to do it this way because I don't want to risk the fan being left on when the engine shut off.
