Duo-Therm 1356 Gas Furnace

I have an old Duo-Therm gas furnace that is used for heating a cabin in Michigan.  Somebody tried to rewire it with speaker wire, and I'll give them an A for ingenuity, but an F for not doing it right.  Short version is, I'm now stuck with a thermostat, a WR 90-113 fan control relay/transformer and 2 wires hanging out of the gas valve.  I'm not sure there were schematics when this thing was originally made, :confused:  but I know I don't like freezing my rear off and I really don't like frozen, busted pipes.  Anyone point me in the right direction on the wiring hook up?  I'm guessing the 2 wires hanging out of the gas valve are the high and low limit?  Any help is greatly appreciated.

 

FYI, Google was no help.

 

Thanks in advance,

 

Matt
