A method and assembly for protecting a device connected to a wiring harness is disclosed. The assembly includes a protective shield having a bore for receiving the device and a positioning device. An elongated wiring harness extends from the device being protected and through the bore of the protective shield. The positioning device is formed having a band that surrounds a central space. At least one flexible, resilient finger extends radially inwardly from the band into the central space. At least one of the fingers forcibly engages the harness sleeve to maintain the positioning device and the protective shield in a predetermined protection position along the harness sleeve at least partially surrounding the device being protected.
