Very cool, Cycle. That is good info to know. I wonder,on the basic radios that do not have the VSS wire in the small plug, if the wire is still at the instrument cluster and goes to nothing, or if the pin is empty where the wire would normally be that goes to the RF radio? Then I wonder if that pin is still capable of producing a VSS signal on trucks with the basic radio even though there is no wire there. Because if it didn't, the clusters must be slightly different internally. I would think they would use the same cluster but just eliminate the wire that goes to the deck. And that the pin is still capable of producing the VSS signal. HMMM?
