Wires too short to remove my Dometic furnace

We have a 2019 Cougar Half Ton 26RBSWE and need to pull the Dometic furnace. It started giving us trouble yesterday and today won't light at all.


The fan will come on and run, but there is no clicking from the igniter. Earlier, we could turn it off for about 2 minutes and try again and it would work, but now, we've tried turning it off for several minutes and even pulling the 12V fuse for a few minutes, but it just won't light.


We think it must be the controller board or the sail switch. I would like to pull the furnace out so I can see both, but can't get there. The access is under the fridge on the inside of the camper. I've removed the air return grill and then did the following:
1. Removed the heat ducts;
2. Removed the gas line
3. Removed the two mounting screws on the bottom/front of the case.


The unit will move out toward the inside of the camper, but will only go so far before the wiring is pulled tight. I can only get the front of the case about 1 inch outside of the opening. Not nearly far enough to get at the back of the unit.


The wires don't have any type of connection block/plug that I can see. They go straight from inside the top of the furnace case up into the outside cavity for the fridge.


How do I pull this thing out? Any help would be greatly appreciated.
