X2 on the 7.3l glow plug relay either go aftermarket or keep factory spares cause that relay will cause you all kinds of headaches, usually when you really need the truck.

also w/ the 7.3l's make sure the glow plugs actually shut off once the truck runs for a minute if they don't it will kill the plugs pretty fast.



also sorry to hear about the thieves in your area, that sucks maybe the police will get'em though.
