I'll probably end up just cutting it off but I'm kind of curious now. I found it on a 12vdc water pump.

That is called an SAE connector. See this page, SAE Connector section down the page.

Motorola uses them on their two-way radios, so they're rather common.

    \$\begingroup\$ They're fairly commonly used for aftermarket 12V equipment in general. Their design makes it difficult to short the 12V and 0V connections. If 12V from the battery is provided in the enclosed side, then it's also difficult to short against body metalwork. The OP's picture is probably the "equipment" side connector with 12V exposed, intended to plug into an equivalent connector from the battery with 12V enclosed. \$\endgroup\$

Those are SAE J928 connectors.

A rare example of a connector that is both self-mating and hermaphrodite.

Note: they are not just "SAE" connectors because a range of different connectors are also "SAE" connectors. Therefore, do specify that they are "J928" SAE connectors.

    \$\begingroup\$ What do you mean by "self-mating" here? I'm not really familiar with the term, but it seems like it usually means "can mate with other identical connectors," so it's not quite obvious to me how a connector could be self-mating but not hermaphroditic, or hermaphroditic but not self-mating. \$\endgroup\$ Apr 16 at 13:47

    \$\begingroup\$ Self-mating = mates to itself. hermaphroditic = has both pins and sockets. "self-mating but not hermaphroditic" example: Anderson Power SB connectors. They mate to themselves so they are self-mating. They have neither pins (male) nor sockets (female), so they are not hermaphrodite. \$\endgroup\$ Apr 16 at 14:51
