Harness Info

What's the difference between a 6Y5-82553-N0-00 Gauge Harness and a 6Y5-83553-N0-00 Gauge Harness.
Also where is a good source of information for the various Yamaha harnesses, in terms of technical description, etc.
Thanks

6Y5-83553-N0-00 is the harness to connect gauges to key switch. 6Y5-82553-N0-00 is a bad number.
