Furnace Wiring Question
Hi - My dad has a 1998 Cardinal LC and pulled out the furnace earlier this year to have it repaired. Unfortunately, he didn't document which wire went where.
The furnace, a Suburban 35-F, has 4 wires: 2 blue for the thermostat, red for +12v and Yellow for -12v.
The trailer has the two thermostat wires (easy enough here) in the black sleeve in the picture, but also has 2 heavier gauge wire pairs. One pair is orange/white & white. The other pair is yellow/white & white. The orange/white and yellow/white wires are still twisted together from wire nuts and the two white wires have been cut.
In the picture, the trailer wiring is on the left and the furnace wiring is on the right.
Any ideas how this is supposed to go together?
