2001 silverado manual to power windows/locks

[przybo5]

I have a 2001 silverado extended cab v6 that is a base model. It came with no power locks or windows. I am trying to convert them. I already have panels,switches and the harness out of a 2002 z71. My problem is I found out my fuse box won't support this. I can provide pictures if necessary. I'm looking for advice on if I can just get another fuse box out of a truck that has the options and do I need to get a new underdash harness as well? 

Also if anyone has done this swap before any other insight would be greatly appreciated 

 

Its a project truck and has sentimental value so I'm not just going to " go sell it and buy a truck with all the options"
