I've used the 21 circuit universal Painless on a number projects. Most were LS swapped projects. I saved all the connectors off the original car/truck harness and the mated them to the Painless harness as needed. Get a wiring diagram for the original truck harness. These trucks are pretty simple. I think the direct Painless harness is configured to plug right in the truck components.
