† The -017 AMM is a plastic unit, similar to what is used on LH 2.4 and later, but it is adjustable. It is not interchangeable with the -005 AMM. It was only used on non-catalyst Saabs.

1988B - This denotes a change in certain systems, particularly engine management, that occurred mid-year 1988. I don't have an exact breakdown of when it happened. Simply check the components. Primarily, the 1988B cars were Swedish market, not US market. One of the significant changes is the change, with the B202i motors, from the ignition being triggered by a sensor in the distributor to a sensor mounted on the oil pump cover. This required changing the EZK system and wiring.

The background colors in the cells are there simply to emphasize the same component being used in different years or with different systems. Colors do not repeat for each component type, but are used in different columns. No other significance should be ascribed to the colors.

Do not ascribe undue signifigance to any component changes. Often, they are made for packaging reasons, and performance will remain unchanged.

A note on the Bosch number: The Bosch number is listed as the last three digits of a typically 10-digit number. For example, a 1990 9000 turbo's full Bosch part number got the LH ECU is: 0 280 000 586. For all components of similar design, the first 7 digits should be the same. but remember, the first 7 will probably be different if the component changes significantly.
