Used in E31, E32, E34 w/o traction control. The yellow zinc plated solenoid bodies are unique to the 022 series of pumps, as are the solenoids inside, and are additionally sleeved made of aluminum that cover the solenoid frames. Many pump internal and external components are shared with their E30 brethren, but the main pump casting and upper manifold plate are specific to the 022 series of pumps. 4 channel ABS operation w/o traction control. The upper manifold plate was used on other vehicle models with multiple potential fluid port directions, but all ports are on the side for this pump variation. The cover shroud and chassis wiring hold down are secured with T15 torx screws
