Hello,
I got a 09 W900 that the one fuel gauge is not reading. It has 2 gauges. The sending unit is fine, as I can swap the wiring harnesses side to side, and the problem follows the wiring harness. I am guessing that this circuit would go to the chassis node, but I cannot find the node. Any Idea where to look, or a wiring diagram? Last six of VIN. 238694
