Hey guys new here, looking for anyone who might be able to help with links to wiring diagrams for the 2019 model. Found a lot of older ones, but we got a real good deal on a WT edition, but we are trying to install oem components due to warranty. Trying to find the driver rear harness connector pin out (for electronic tailgate lock) & possibly upgrading the steering with audio controls. I don't mind taking time to pin things properly, just need the schematics and GM seems real pissy when you ask. Thanks again, hope to share anything I learn for those here.
