I need more info on how to put a manual fan switch for a 3.4 camaro,Thanks

 

There are several ways to do it with out actually buying a switch. All you really need to do is tap into the wires going into the fan motor and give it power to turn it on. Run a wire to the interior to a switch and run the wires from the switch to a power source and a good ground. I was about to install a switch in my car then i realized with the temp at 180 puting the vent control on one of the two defrost settings turns the fan on.
