I have recently come into the luck of owning a used cluster from I believe an 05-06 997 Carrera. They were sold to me with no guarantees in "as is" condition which meant a cracked oil pressure lens and the gauges stuck at random metering. I presume someone was doing 100 MPH at 5000 rpm right before their Porsche went into a wall and the gauges froze in that position.
I would like to test these gauges myself by at least sending 12volt to it, but without a wiring diagram I cannot determine what any of the the 32 pins do. I rather not damage, what in all ways I can determine, are a perfectly fine set of very expensive gauges.
I have removed the rear panel to check for any hidden physical damage and found none. I also took the chance to reset the needles to 0.
Anyone that can enlighten me on the functions of each pin or provide a schematic (I guess hand drawn not to violate the forum rules) it would be greatly appreciated. Once the status of the cluster has been verified I will replace the lens and either resell it or use it for a small computer project I have been working on or just keep them around as a piece of artwork.
