Instrument Cluster Bench-Testing Logs
The wiring for this kind of testing is divided below by the specific cluster tested. Similar clusters from different series are likely to be the same but your own due diligence will be required. Clusters will be added as they are tested.
Certain pins have proven unable to test, in these cases the pins will be marked as UNKNOWN
Clusters tested:
