I have paper copies of the full chassis schematics (four sheets 18"x24") for the 1997-2003 pre-vansco Alpines. They are readable but just (takes a bit of interpolation on some of the smaller print), and I couldn't find a scanner setup to get them to a readable PDF output for the Tech Library. You can PM me for details if interested.
These are not the cable layout for the battery compartment, which are on the Library IIRC, but are the full working schematics showing relay blocks, runs to the Allison Interface Module, blah, blah, blah.
