Yes, with some conditions. Many who are mounting the VT Pack externally are placing the connector collar through a knockout or a punched hole in a socket or cabinet. If that is your preferred mounting, we actually make an external mounting kit to make it quick and easy. Since the VT Pack connector and mating wiring harness connector are not designed to be directly exposed to the elements, they must be protected. If the VT Pack is to be mounted where the collar and connectors are to be exposed to the elements, we recommend that you use our connector cover. This rugged UV resistant cover covers the connector as well as the harness from the elements. In addition, if properly installed, will provide security from tampering.
