Well after I complained I got a nice mail reply that said Subaru only gives a complete set of wiring diagrams (may be other things too) for the inital year, and they "try" to keep subsequent years up tp date. Seeing as the 94 is not the inital year, and my '96 is already 6 years ago, I think this was just PR talk.
Anyway, if you subscribe, you can check if you have at least
54 electrical diagrams. I'd like to know if your year gets more.
If not Email a complaint. As of today, nothing has changed, but
to their credit, they gave me a free '94 subscription with my '96.
Perhaps they need to sell certain years as just supplements.
