The wiring scheme for the Clarion 2 systems is the same on the 82 and 83's. When you buy the complete setup from some one always make sure it comes with the additional wiring harness adapter for the power feed splitters in the fairing, then you don't have to jury rigged the power leads.
The install manuals off GSMcleans site shows all the components and where and how they install.
Also be aware that the input socket on the distribution component (main intercom unit) can be used with an adapter cord off Ebay to plug in the audio feed from a mp3 player or gps unit. Already done this on my 82 and it feeds the gps audio straight to my headsets.
