Thanks for replying guys. I might get in touch with Mazda, but it's very unlikely they'll help me. When they see an import, they roll their eyes...
Cosmo dude, if you have it in electronic format (climate control wiring or air-con wiring diagram), would you be able to email it to me or post it somewhere? I would assume they'd have Katakana writing on it - if so, I'd get somebody to translate it. Cheers
