Im wiring twin thermo fans in my VL Calais and have previousley had them running from the same circuit as the indicators and head deck (accesories power) I do want them running all the time. But when i have the motor off and the key in the ON position the fans are running at full blast which drains the battery very quickly. My question is, is there a wire somewhere in the car that only has + power to it when the motor is running?
