Abstract: A probeable electrical connector assembly including a set of or a plurality of mating terminals (6) and (8) arranged in a matrix and accommodated in mating housings (2) and (4). Passages (12,14) having openings (11) are incorporated in housings (2) and (4) and allow the insertion of a probe (16) to make electrical contact with a preselected terminal of a joined terminal union (10). In this manner electrical measurements may be made with respect to the terminal without first disassembling the connection. Undesired contaminants are prevented from entering openings (11) by a reusable seal (20) which is positioned about each housing.

Abstract: An automobile junction box (2), programmable in relation to vehicle options that may be required, houses printed circuit boards (24, 25) having receptacles (28) for receiving tabs (36) depending from an elongated member (34). The tabs connect the circuit pathways (26) corresponding to vehicle options. The selected circuit pathways may be modified by the inclusion of a second set of receptacles (29) on the printed circuit boards for receiving electrical components (14) such as diodes, resistors, zener diodes and the like.
