The following series of post represent over a year and a half of research. I started this project due to the numerous requests for diagrams, connector pinouts, & component troubleshooting. This will be an ongoing process and will remained locked from general comments until complete in order to keep information properly organized.
I'm moving it into the maintenance thread so that members can begin to use the information while it is being updated to include the following information:
Full diagrams for engine harness 2013 - 2014 & 2015 - 2018.
Connector view and Pinouts associated replacement pigtails.
Physical locations of components & troubleshooting procedures where applicable.
