Here's a site a ran across while researching something else. If you need wiring connector info including circuits and connector pin outs check this site out. It's good for Mopar vehicles from 1997-2019. Cars, Trucks, etc.
Just enter the Year and platform and you'll get a listing of all the connectors in the vehicle and their pin outs, wiring colors, etc. Also will tell you if any wiring repair kits are available for a particular connector.
