It's sort of depends on the years. The newer(push in blade fuse style) fuse boxes have a spot for the wiring to clip right into. Which is different from the earlier design. I don't know what the year split was. The wiring comes as a complete unit. The only part of that that is a pain, is that it runs through the upper part of the dash. The dash pad has to come out and the wiring runs behind the guages, over the top of the heater and down into both kick panels to the doors. Holes will have to be drilled in the door pillar and in the doors. I have only been able to do this with the doors off. As far as the parts in the doors. You will have to pull the windows out and put the whole power window regulater in. The door lock selonoid just bolts in and has a single rod. No biggie. Not hard, but can be time consuming. what years are the donor and the truck your installing into??
