First of all...good car choice. Second of all...join us over at http://bbs.legacycentral.org.
It's a forum for those of us lucky enough to own BC-BF Legacys. There's a TON of information over there and everyone's pretty helpful/knowledgable.
To answer your question, IIRC the Honda CRX gauge pod works well with our cars. At least that's what someone said over on our Legacy board. Good luck!
