7-Way RV Trailer Connector Wiring Diagram
More times then not when the 12V pin on a 7-Way isn't active it's the result of a blown or missing fuse under the hood. Check your vehicle's owner's manual for the fuse locations and make sure the one connected to the 12V trailer circuit is present and in good condition. Let me know if it looks good or replacing it doesn't help. 61788
