If anyone is interested in a color coded pin out of the under hood fuse box let me know. I have almost completed one with the exceptions of a few relays. I will have to research to see what years are covered but 2002-2005 chevy and gmc trucks and suv's should fit the bill for the current diagram. I'm going to upload an attachment for example. it is not complete but the information already there is accurate. if just one person wants it I will repost when I have completed it. I also have one for the indash fuse panel located behind the dash cover on the drivers side.
