Oh yeah, BajaExplorer, that panel you mention in your original post, it just pops off the small latches, just pull forward, Gently.
Then you have the power wire on one of the alarms there, I think its the Lg gas alarm, but there should be enough slack to move it a little. You will have to slide that air handler hose off the vent on the panel.
That hose is annoying. Since I don't use the forced air furnace, that hose is compressed with a couple binder clips, and moved to the side so you can get to the water pump. The one air handler hose you see in my pic, is the hose going to the rear bedroom. Its kinda out of the way. The wheel well is right behind it.
That panel right below the refrigerator is removable, you just pull it off gently, and install is reverse, lining up the tab on the right first and pressing it on.
I added wire and put a connector for the power to the LG gas alarm, that way I could move that panel completely out of the way
You will see everything under there, its a rats nest, mine was. LOL
post any questions, welcome to the forum, have a good one !
