The invention relates to an electrohydraulic unit for regulating the brake fluid pressure of a motor vehicle. The device includes a hydraulic block, on whose one side an electric motor is affixed. The electric motor includes electrical connections which protrude through the hydraulic block to an opposite side of the block and are connected there to electrical conductors of a mounted control device that covers the electrical conductors. For a simple contacting of the electrical connections, the conductors are helical wound around guide pins, which protrude into blind bores in the hydraulic block for the positioning of the mounted control device on the hydraulic block during assembly so that free ends of the electrical conductors reach into forked ends of the connecting pins before the mounted control device covers the connections. Contact points are therefore accessible for the production of an electrical connection during the assembly.
