I need wiring instruction from thermostat to furnace on my nordyne M1MB gas furnace. A friend hooked it up for me, but there are only 3 wires - red,green,white going to corresponding wires and 2 -yellow, blue he didn't connect to anything. I'm pretty sure the grey (c) wire in the furnace should be hooked up to the yellow wire but I want to make sure because Google is just confusing me and the manual is too hard for me to follow on a cell phone. That and I don't want to fry myself. 62 yr old female DIY-er can do, but need a little help here...
