no you cant just plug in a new one and leave the old one on. as it has 3 terminals that plug into the distributer. i belive the relocation has to do with the heat transfer issues, personaly seems to be more work than its worth to just get the truck running but if thats what you want to do more power to ya. the one thing that is a pain in the ass about them is that you need a thin walled socket to remove the 2 bolts that hold it on. the tech page says that its a 7/32 and that you can only use that special tool. but thats not true, i picked up a deep socket from auto zone and had no problems using it. ive also seen them held on by a torx head bolt, not sure which one is more common. but once the 2 blots are removed it should slide straight down and the new one will slide straight up in. but be sure to coat the metal surface that rests agenst the distributer with an electric conductive grease. otherwise it will burn out agin.
