Spark Plug Change in a Truck--How Hard Can it Be? Update#2

But is it really as tricky as all that? I saw a post from here using Search that said you don't have to take the coils off, just do a 1/4 turn. Not clear what that means--the coils stay on the wire and you are left with the spark plug to take out same as always before?

I just don't want to do any damage. I suppose if I am replacing the wires with the kit anyway, it doesn't matter if I wreck one taking it off, only when putting the new one back on, but what do you actually do to get at the plug?
