The LED should only turn on when the fan is activated.
Did you change LED18 to Output 4 in the Code Config screen? Does your fan turn on when it should?

OK, just making sure, sounds like its time to break out the multi meter and check voltage at the relay and fan. Make sure the relay turns on, maybe its bad. Test the fan and test the relay. Sounds like you have it hooked up correctly. I used a relay from a camaro once and the fan fan drew too much current and burned it out after only a couple runs.

I don't see why you would need that 1k resistor nor have I ever installed one. All of my boards have tested out fine on my car as well.

You do not need the illustrated 1k resistor when using the output as fan control. That is only relevant for an ignition output going to a module.
You must though, install the 1N4001 across the relay contacts to prevent damage to the transistor.
