I guess I am one of the lucky ones. I went to install the switch today on my ‘15 Silverado 1500 LS. My truck already had wiring for the AUX locations in the connector. I’m assuming GM uses the same harness for the WT and the LS as they are both lower end trucks. I’m having a friend that works at a dealer see if he can find the wiring diagrams for the harness. So I can install the relays and fuses and pull power from the relay. Has anyone else run into this?
