The first step is to install the cooling fan to the radiator of the engine. To complete this process successfully, you need to find the positive and negative wires. The positive wire is the ground wire, and the negative wire is the power wire.

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

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!
