A sensing terminal system is disclosed for an electrical connector. The system includes a first terminal adapted for connection to a voltage potential. A second terminal includes a first part and a second part, with the two parts being electrically isolated. The first part is adapted for connection to a sensing line. The two parts are electrically coupled in response to mating of a mating terminal with the second terminal. The second part of the second terminal is electrically coupled with the first terminal to complete a sensing circuit therethrough.
