I just did my own harness on a 2004 5.3 Vortec. If you are fairly confident in your skills and have patience, it's easily doable. If money is not a real issue, buy the Painless.

Mine was time consuming because I removed all the wiring that I didn't need or wasn't using, and then rewired the Power Distribution Center and combined it with a new underhood fuse panel for the whole Jeep. I could have done the whole thing in a few hours if i just wanted to make it run...

Here's my new fuse box (PDC)-

PDC closed- connects to the engine and harness with various Weatherpack connectors for a modular system-

My modified harness- still have to put connectors on all the wires on the left corner, but they will plug into the PDC when done-
