Hi
I am installing a Derale oil cooler # 15950 with a Derale fan controller # 16749. The wiring for the controller calls for a switched positive to the Yellow wire off the relay. See picture. I know my coil is a switched positive - But is there another switched positive inside the relay box in the engine bay ?, or is the coil the best option?  |

My oil cooler came with a thermostat. I installed the thermostat on the outlet side of the cooler and had this control the fan. I used an unswitched circuit with a series fuse. The fan will run after stopping until the temperature is lower. I put the sensor on the outlet because the oil from the engine will always be hot enough to trip the thermostat. The oil cooler will remove some heat without the fan. I let this work until the fan is needed
