I have this listed furnace, I know its old, no money right now to replace. Problem is after lighting and the thermostat kicks furnace off the pilot light goes out. This unit has many different wires coming out of it. Worked fine last year, we had a serviceman look at it, all he wanted to do was sell us a new unit and he unhooked some wires. I just want to make sure the right wires are going where they are supposed to go. Thanks,
