If this is for solar panels, you may be (probably) already prewired.
So, drill out the rivets and remove the refer vent cover.
Find the prewiring if so equipped.
Otherwise, run your wiring though the screen and down the forward side (toward the tongue) of the refer compartment. Then snake it forward in the channel already provided for electrical wiring between the refer compartment and the 12 volt
panel under your front sofa.
Remount your refer vent cover with Olympic rivets for best appearance.
Easy, peezy, lemon squeezy.
