Thanks. That diagram Tommy uploaded is basically representative, but it's for an earlier model with the individual gauges. Now that he knows it's for a 2006, perhaps he's got access to a newer diagram that incorporates the cluster gauge wiring - because unfortunately I don't. There is however a problem with how the above diagram depicts the tach/hour meter wiring. Look at the K terminal on tachometer sender 21. The line going down to that tail light wire is incorrect. That wire is the hour meter trigger, and should go over to oil pressure sender 24.
