BBC ECM Applications

[Walter Sherwin]

I wonder if I could impose upon the collective for a wee bit of info?  I
know many of you guys have cross reference books and magic decoder rings for
this kind of stuff.

I'm trying to help out a f.o.a.f. who is convinced that he has a 92  Gen V
L19 454 & harness & THM400 (not a 4L80E) that was yanked by a wrecker, that
came to him sans ECM.

Was there such a thing as a 92 C/K 3500 dually with L19 & THM400?  I thought
that by 92 all big-blocks got the 4L80E, but I may be wrong. If so, what ECM
did it use, and can anyone tell me a typical BCC reference for same?  There
are two computer connectors on the harness that he has, both black, and one
has 24 cavities while the other has 32.

Sort of related to this, can someone verify what ECM the 90 454SS with
THM400 used (747 confuser ?).  Also, can someone tell me exactly what BCC's
are shown for the 90SS.  I'm assuming there will be three???  One for
federal, one for left coast use, and one for leaded export?


Thanks;
Walt.
