my buddy is looking to buy a 2005 35004x4 regular cab Cummins,it has manual windows,he wants electric windows,doors can be bought from a salvage with electric windows and the parts transferred to his truck,the question is does the manual windows truck have the harness that you can just plug in the stuff from the donor doors,or will you have to get inventive with the wiring to make them work?,he wants electric door locks also,i presume its likely that he will need to use the donor door panels so the switches will fit correctly
