The 121-way sealed plug-in connection is suitable for the connection of control units mounted in the engine compartment. The plug-in connection consists of a 40-way module (8x JPT and 32x BMK contacts) and an 81-way module (5x JPT and 76x BMK contacts). A silicone gel seal (BMK 0.6) and individual wire seals (JPT) are used for the cable. Thanks to the gel seal, no additional sealing (e.g. dummy plugs) is required for non-used signal pins (BMK 0.6). A slide is used for pull-in and locking.
