16-14 gauge unsealed female 56 Series terminals #2962447. Metri-Pack terminals are different from Weather-Pack terminals in that the male terminals have flat pins, similar to a quick disconnect, rather than Weather-Pack's round pins. These unsealed terminals require unsealed housings. Terminals require two crimps (terminal to wire strands, terminal to wire insulation). A proper crimping tool is required. For heavier usage, use a tool that performs both crimps at the same time.
