Recently acquired a 2012 1500 ST and am working to clearing a number of codes. One is p1457 (fuel tank pressure system) and in tracking things down discovered three wires pulled out of a plug that is attached to the natural vacuum leak detector (part# 4593494AA). Have not been able to locate a wiring schematic for the fuel tank area and need to know the wiring order for the plug, i.e. which wire goes in which hole. Yellow/red stripe, blue/orange stripe, brown/tan stripe. Local shop replaced fuel pump 11/2021 and I'm guessing this occurred then.
