I have 2005 denali w/6.0 . and it has RVC regulated voltage control. I'm almost done with my harness and want to know if it can be deleted or not.From what I understand it only came on some of the 2005 trucks.I spoke to a tech at GOOD CHEVROLET and he told me that he did not know if it can be deleted the only thing that he knew is that its for the charging system. the 6.0 is going into a 72 k-5. thanks
