I have read numerous threads on other sites and non have helped. I have a 2010 Silverado LT crew cab Z71 4x4 with the 5.3L flex fuel and 6 speed auto that I bought used. The truck does not have the DIC buttons and I wanted to add them, so, after reading a lot of threads on how to this I looked behind the panel to see if the harness and pigtail were actually there like everyone says it should be. It isn't.... does this mean that I can not add the DIC buttons to my truck?
