Recently acquired 2012 RAM 1500 ST that had CEL on. Tracked problem to p1457 (fuel tank pressure system) issue and found that the wires had been removed from plug attached to the "natural vacuum leak detector" (part# 4593949AA). I have plug but don't know which wire goes in which hole on the plug. Wires are coded yellow/red tracer, blue/orange tracer, brown/tan tracer... Suggestions where I can find a wiring schematic?

Device in lower left is the natural vacuum leak detector (part# 4593949AA)

 

Have a look here. (I am hoping that is a direct link to the correct diagram.... if it ain't.... That is in section 3 of the 5.7L engine wiring diagrams.)

 

That is exactly what I needed!

Thanks for your invaluable assistance
