Where can I get a SCHEMATIC for the 90-91 Y-body 7727 ECM and harness?
I need to make a harness for a 90-91 Vette 7727 ECM, but can't find any breakdown on the harness and ECM pinout. Hey Glenn, BOWTIE and everyone, could you help me out? I'm hoping that their is a link with this schematic out there? I know that the 7730 is the equivalent, but the person I'm helping wants the WATERPROOF 7727 ECM. Thanks guys.

I have been looking, but no luck yet. I have a shop manual for the 730 ecm used on my 1991 Firebird, but that won't work. There are differences between the two such as the Y-body monitors oil pressure which the F-bodies don't.
Try posting on the General Tech and possibly Vader or GMTech may be able to scan a couple of pages from the 90-91 Y-body shop manual.
I even tried ftp.diy-efi.org/incoming but have found anything for the schematics to the 727 ecm pinouts. If I find something, I'll let you know.

Thanks...I would like that for my own personal archives. Glad to see that you made it here to the PROM Board. Ready to burn an eprom yet? Let's chat via e-mail so not to clutter up the PROM Board.
