Fuel Injection Relay Applications.

FI relays can differ by model. According to the Pocket Date Book from Volvo, all F/T engines (both Bosch and Regina systems) through 1993 use the -608 white relay regardless of turbo/non-turbo. For 1994 and after, B2XXF NA-engines use the -270 relay and T turbos use the -608 relay. All E engines use the -639 relay. However, some 760 Turbos use the green 1362914 relay. Per John Marshall in New Zealand, some of the later 9 series (1994 onwards) have a different layout of relays and use a blue Hella fuel pump relay, mounted second from the right in the front row. The one to the right of it is the same Hella relay, used for high beam lighting. The Hella relays on have 5 pins in the base and are marked as follows: Hella 12V/ 4RD/ 003-520-52. Even a diligent search of Volvo Technical publications (e.g., the wiring diagram, that for other electrical equipment, etc.) will not show this change in the color, size, and location of this relay (versus the white, rectangular, second-row position, for earlier 940s). Note that relays are not interchangeable.
