It’s very instructive but unfortunately when I tried it I found the furnace wiring harness was too short to pull the furnace out of the compartment. May be different on yours and this was by no means difficult to try. Worth a shot.
Taking mine into the dealer tomorrow. Hoping they can extend the wiring for future maintenance.
