Great post. My new 2010 Ram 1500 SLT Crew was suppose to have both connectors installed with the "trailer tow wiring with 4-pin connector" option, but is missing the second small grey connector. No, my dealer cannot explain why. Would you have a clear photo of the back of the small grey harness connector? I've figured out which wires to run, but haven't figured out how they map to the pins on the connector. Again great job documenting your efforts.
