An electrical connection structure for connecting an electronic control unit 7, for example in an anti-lock braking system (ABS) or a traction control system, to magnetic valves 2,3, or other load, features a novel plug-and-socket structure which eliminates some of the conventional wiring harness. Magnetic valves 2, 3 are attached on one side to a housing 4 and feature, on their opposing faces, prongs 6 which engage counter-contacts 18 on electronics unit 7, which thus attaches directly to the valve unit. Electronics unit 7 also has sockets to receive contact pins 22 of a relay 23. Electronics unit 7 and valve housing 4 mate in such a way that relay 23 cannot be accidentally unplugged and is protected from environmental influences.
