wiring for T@G XL Outback 2017 . Most of the wires are in the space behind the kitchen and inside wall. There is about 3.5"to 4" space , the WFCO power box and radio come out by removing a few screws.I ran the new wire for the Norcold up under the power box and over to the hole behind the Norcold.Look under the T@G by the AC vent you will see a split loom that runs to the battery , drill the hole next to the split loom.Take out the power box stick your hand down and feel where the wires come in, Pull the AC cord be for you do anything.DON,T use tape use lots of tie straps seal the hole very good.
