I'm 99% certain that they will sell you the guides, and fairly certain that they will also sell you harnesses and adapters as well. I have an all-new 2001 model car, though, (Mitsu Eclipse Spyder) so I'm not sure if they'll have a guide for me. I should give them a call.

On the other hand, the dash is easy to open (I've already done it), and I don't want to install an amp or speakers -- there's already an amp under the passenger seat.

It's just the wiring that I'm going to find tricky.
