I don't have pics or video but I replaced my LDP last year. It is mounted on the bottom side of the battery tray, it was not hard to do. You have to remove the battery, unbolt and remove the battery tray, then take the bolts out of the Power Distribution Center and move it out of the way but no need to completeley remove it from the truck. Then remove the battery tray and the 3 bolts holding the pump in place.
It is in the 2001 Dodge Service Manual, you can download it in the FAQ section, or use the search function and find a link to it here in the forum.
