Are you talking about wires on the thermostat?
I think that part number is ***** the thermostat..........what is the model number of the A/C?
O.K..........isn't there any wiring diagram on the control box up there?
Let me see if I can find you one.........
Are these wires up on top or inside the coach under the ceiling grill? The blue is a furnace lead. And when you say "in" here.........what does that mean?
You mentioned sticking a wire "in" and not sure what that means. Can you take a photo of the control and attach it to your post?
Use the paperclip icon............or e-mail it to me at***@******.***
I can't tell much from that photo really. Part of the problem is that Coleman has dozens of models and they changed over their website and hard to find anything now. Those terminals should be marked. I will opt out of this and let another tech offer something as I have to go out on a Service Call. Sorry I wasn't able to come up with the correct wiring for you.
