Yes, it does. This manual provides the full set of color-coded factory wiring diagrams for the 2020 Ram 1500 equipped with the 5.7L Hemi engine.
It provides the detailed schematics for the engine management, power distribution, and ground locations, along with the specific connector pinouts for every module on the vehicle. You’ll have the exact technical maps needed to trace circuits and identify wire colors, which is a lot better than guessing where a fault might be hiding.
Whether you're chasing a short or just pinning out a sensor, having the manufacturer's data is the only way to get it done without chasing your tail for hours. Hope that helps!
