I have a 2006 Cayenne S that has an issue in the wiring harness to the low pressure fuel pumps in the fuel tanks. Error code P2632 Fuel Pump "B" control circuit open. Apparently there has been water infiltration into the wiring harness. The first Porsche mechanic mentioned that the wiring felt warm. The second Porsche mechanic found the Error Code but stopped when I balked at their cost to investigate. Can someone direct me to a wiring diagram for this circuit.
