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.

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.

Can anybody help me figure out where these two mystery wires should be connected?
