I can scan what I've got but I think you are better off doing what I did - drop in on the service department of you dealer. Here are a few reasons why: a)what you will get from me is a scan of a fax of a photocopy, b) I have an RX300 w/o Nav. In my car I know that the amp is under the rear seat and connected to the head unit with a wiring harness that passes behing the glove box. I have no idea about the layout in your car.

As mentioned in another thread I did succeed in injecting audio into the harness in place of the CD changer. But if you remove the changer then the head unit won't allow you to select "CD". Better to inject the audio through the head unit's radio/tape leads and select your source with a signal relay or switch.

The changer is much larger than the empeg but (at least in the RX300) won't be terribly visible in the glove box,
