I probably should have asked before buying anything but I bought this relay to switch on a 12v pc fan that is triggered by the receivers 12v trigger.
That relay should work right? I did some reading and people recommend adding a diode (1N4001??) to prevent current from going back into the trigger. Is this right? If so, where would the diode connect to exactly? I'm new to all this so any help would be great!
So I found this image which I assume is correct.
