Sealed rear-loaded electrical connector housings, assemblies and systems are disclosed. The housing includes a connector having a TPA cap including an aperture and a TPA leg, a rear wire seal including a wire aperture and a TPA leg aperture, and a housing including a positioning surface. In a pre-loaded configuration, the rear wire seal is inserted into the housing, and the TPA cap is mounted onto the housing with the aperture aligned with the wire aperture and the TPA leg disposed at least partially in the TPA leg aperture. In a loaded configuration, the TPA cap is mounted deeper onto and locked in place on the housing, and the TPA leg passes through the TPA leg aperture forming a water-tight seal with the TPA leg aperture. The assembly includes the connector and a wire-crimped terminal disposed in the connector. The system includes a first connector and a second connector.
