A Step-by-Step Guide on How to Straight Wire a Cooling Fan

Although it looks complex and technical at first, all you have to do is follow the below-mentioned steps. And in no time, you will be able to have your cooling fan all set up and in good working condition.

Make sure that you have selected the two wires carefully without getting them confused.

Once this is done, you need to cut and strip around half an inch from the insulation ends of the two wires.

Step 2. Grounding

Take a twelve-gauge jumper wire and connect one of its ends to the ground wire of the cooling fan.

Connect the other end of the jumper wire to the engine of the car or any metal part of the vehicle. (1)

Now take another new twelve-gauge jumper wire and connect one end to the positive wire of the cooling fan and connect the other wire to the battery of the vehicle. Now you can place the wire on the battery and begin the testing process.

The cooling fan will begin to work once you place the other end of the jumper wire on the positive end of the battery. If the cooling fan works, it means you have done everything right!
