I am installing a new wiring harness and the directions say to just connect the fan relay wire directly to the fans themselves. I did this but am getting no power to the fans. Fans are good And grounded properly. Obviously I would need something to trigger the relay to turn on the fans. But, where do I hook temp. Into? There are no other wires in the harness that pertain to fans or cooling for that matter. Thanks for any help or input.
here is a diagram, hope it might help you. If you have a temp switch, it needs power in one side and the other side hooked to the trigger on the relay. Also if you have a/c you need a switch to turn the fan on whenever the a/c is on or the system will overload and blow a hole.
