Radiator after run relay.

Marginally.  It probably wasn't even installed, to fall out like that. 
Might have been a spare, or dead (always ran?) and removed.

There's a little sensor at the rear of your car's head that feeds that 
relay, it runs the fan when the key is off if the sender tells it to.

Again, I'd wager the relay or sender is bad and the PO removed it.

I goes somewhere in the aux relay panel behind the driver's knee panel, 
I believe.  If you live in the northern hemisphere you have a few months 
to figure it out before it could even matter at all.  Except a few 
places, like Death Valley, I suppose.
