Heil Furnace GU105dd2.

I need a wiwing diagram for this furnace.

I have had it hooked up with a plug, so when I wanted heat I had to plug it in and when it was warm enough I had to unplug it. \

Now I want to hook up a thermostat, so I need to know what wires go where. It is a little more complex than just hooking up the thermostat. I also need to rewire the transformer, fan and another "box"(it is a honeywell brand unit that switches between on and auto) correctly. I rewired it to run it directly with the plug.

This is in my garage so don't think this is as hillbilly as it sounds.

Thanks, Jay.

Look on the back side of the blower door. There is wiring diagram put there at the factory.

I could not find any contact info for Heil at their website and there is no wiring diagram on the back of the blower door.

Any other ideas?

I can take some pics if you might be able to tell me what wires go where?
