Re: DI Cassettes

Perusing the parts catalogs, I was able to come up with this 
'history' of DI cassettes. My info is current through the first half 
of the 1999 model year, and includes the 9-5 and 9-3.

With attached cable (DI/APC):
75 84 204 - original P/N exchangeable coils
74 85 808 - 88-92 P/N exchangeable coils

No attached cable (Trionic - 10-pin connector part of cassette)
91 34 404 - 93-94 non-exchangeable coils up to motor S075975
91 78 955 - 95- ALL prior part numbers supercede to this one. This 
unit is used on 9000, NG 900 and 9-3 cars.

If replacing a cassette that has the attached cable, harness number
93 21 787 is also needed.

9-5 Trionic T-7
91 87 980 - same connector style as the 91 87 955, but black painted 
instead of red. Used in 9-5 cars, and the 9-3 Viggen.

As far as I know the ~955 DI cassette is the last of the non-T7 
units. I don't know if there are any other part numbers for the black 
cassette.

As for the DI cassettes being low tech, don't think that they are 
just 4 coils in a pack. The DI cassette tells the DI/APC and Trionic 
computers when combustion has occurred and in what cylinder, and in 
the Trionic cars, the DI cassette **IS** the knock sensor. They are 
more sophisticated than you might think!

Just to confound us more, there is a special Blue cassette. The only 
'special' thing about it is that it is sold through Kent-Moore as a 
test unit. The 'known good' cassette that the tech might swap in just 
to make sure. It's a blue not unlike the Swedish flag, and has parts 
of the edge seal cut out. The blue is so the tech knows which 
cassette is in there, and the cutouts so that nobody can just repaint 
it...Electrically, it's a ~955 cassette.
