Play as Marshal Leigh Johnson

Marshal Leigh Johnson is a badass, and now you can play as him. This replaces John's basic outfits (Cowboy, Wounded, Rancher), but most of his optional ones are untouched.

You need MagicRDR. Open the program, open your game's directory, and go to Red Dead Redemption/Game/Fragments.rpf. Open that up, and replace the files. The quickest way to do this is to right click and import directory, the open the folder with the MLJ files. Make sure you save.
