An insulated cabinet manufacture for use in a refrigeration appliance or the like, having an outer shell and an inner liner with foamed-in-place insulation therebetween. A wiring tunnel is extended inwardly through an opening in the shell, through the insulation space, and inwardly through an aligned opening in the liner. The opening in the liner may be substantially larger than the periphery of the wiring tunnel and a foam stop element is affixed to the inner surface of the liner with the wiring tunnel extending therethrough. A second foam stop element is loosely disposed on the wiring tunnel to be moved into engagement with the first stop element as an incident of the foaming of the insulation material during the foaming-in-place operation. The outer end of the wiring tunnel may be provided with a flange sealingly secured to the outer surface of the shell. A wiring harness is removably installed in the tunnel to provide wiring from exteriorly of the cabinet to the interior thereof.
