Now that the cooler temps are here, I notice that when idling without A/C, my cooling fan does not cycle as it should. I would like to hardwire the fan to be on whenever the car is cranked but am having trouble locating a suitable power source. Can anybody suggest where to plug the positive side so that it only gets power when cranked? Sounds so simple yet I went through the fuse box yesterday and could not find a suitable lead.
