I am in the process of installing electric windows in a manual window truck. I have a 2001 GMC Sierra super cheap model. I have both harnesses switches panels and regulators I am running across a power problem in my fuse block. there are no pins to hold the 25 amp fuse nor is there any pins that are hot that would go to the switch. I am in the process of trying to find a correct wire schematic to locate the power in color wire and also the colors that shoot across to the passenger side. anyone do this yet that can remember the wire colors? Thanks T
