Finished off the install this morning. Routed the cables behind the units. One into the battery bay and one to the rear of the switch panel. Managed to drill the holes for the unit without having to remove the panel, threaded the cables through the holes and hid them away.

Really impressed with the heat it kicks out. Can’t believe I lived without one in my old vans.
Will buy some sealant for the air duct holes and seal them.
If anyone in the local area wants a hand let me know!
