I'm reassembling the Atwood furnace on my 1991 Holiday Rambler Aluma-Lite Free Spirit bumper-pull camper. Prior owner had partially disassembled the components but didn't finish the work. So I swapped out the high limit thermistor, sail switch, circuit breaker, burner/flame tube/grate, igniter assembly, exhaust pipe and blower motor. Upon reassembling everything, I have found a mystery wire that does not seem to have an obvious connection point. See the pics. https://photos.app.goo.gl/z6GXb9QWpMasc1JY6
The charred black wire (I'm replacing it due to the charring on insulation) goes to one of the two igniter connection points. The red wire with a male connection is bundled to that black igniter wore, but there does not seem to be a female connection point anywhere on the exhaust blower wheel side of the furnace or on the gas valve. The yellow wire with a male spade connector also does not seem to have a female connector to mate with. https://photos.app.goo.gl/ACSuyzWQvj6UhWiZ6
The yellow wire is fastened to the body of the gas valve and it is a short wire, so it must connect somewhere on the exhaust blower side of the furnace, close to the gas valve.
Can anybody help me figure out where these two mystery wires should be connected?
