i picked up a 08 2.3 3 cluster from the junkyard and im going to be wiring it into a vw bus if you can please help me out or shoot me in a direction thank you

 

update. i have found that orange and green red go to positive and both black orange go to neg . with those connected i get power and lights and found that grounding black yellow gives me oil pressure dummy. does any one have a manual wiring diagram?
