I finally got off my duff and have got most of it hooked up. The vent is out...the way it should be, this is what I was dreading but like most thing's it wasn't so bad.<br /><br />The furnace is a Payne PG8U The Thermopstat is an old round honeywell. Here is the question. The terminal block call's for a three wire hookup...R..W..C, I used Red, White, and Blue for C.<br /><br />However My thermostat only has two terminals...and they are not labeled. The thermostat does not have a switch, just up or down on the temp. Wich wire goes where and what do I do with the third wire 
<br /><br />If this is not enoufgh info ask away...if you think further info will help. Or I could just go buy a new thermostat that has the wiring diagram included.
