Need help identifying thermostat contron for fan

Years ago I bought a cooling fan, it kicked around the shop till the box fell apart and the instructions are poof.
Some one may recognize the controller or at least how it operates.
Fuse line w/ spade conn. would be power.
Two circuits Y together to a common blk w/ ring conn.
I'd think that would be ground.
If thats the case then the blk/orange and blk/red would power the fan or is it two circuits for two fans?
Thanks for any help.

sorry I flap my jaw or fingers before my brain kicked in. with vom set to ohms. check for resistence between 2 terminals, for the coil.
this is a basic fan relay schematic.
with the coil to +12 and ground. should feel if in hand or hear a little click of the relay closing for the contacts inside it.


hope pic gives better info. :)

The grey wires are the temp probe for the cooling fins.
I'm looking at your schematic, doesn't make any sense to me. How does the temp probe close the switch to activate the coil?
I checked the Hayden site, close but this one is 30 years old at least.
