Glow plug codes??

My '99 Excursion is throwing the following codes:
PO672 #2 glow plug
PO674 #4 glow plug
PO676 #6 Golw plug
PO678 #8 glow plug

Question: Does this mean it is the under valve cover wiring or is there seperate GPR's for either bank??
I figured I would ask the vastly more knowlegable than I prior to digging around.
All help is appreciated!

it means that one or more of your GP's on the drivers side is bad or there is some problem with the wiring on the that side. there is only 1 glow plug module that controls both sides.
