Putting plug wires on a 1997 ford explorer awd that has no wires need diagram for placement

You dont need diagram. If you will notice there is seperate coils for each spark plug. you need 9/32 socket to remove each coil. Theres a small screw that holds the coil in place, Remove the srew, remove the coil, once you remove the coil take a spark plug socket and extension to remove the plug.On the end of each coil is a boot that looks like the end of a spark plug wire . You can buy a set of those boots.Do these one at a time. You can gat a book a auto parts store that could help for about twenty bucks. Hope this helps Leave comment
