hey guys im looking into buying a 93 se 5 speed and ive been reading up on this engine and it seems that the rear coil packs have a set of grounding wires for each coil pack? i didnt see and grounding wires connected in between the coil and upper intake manifold. should i stay away? or do the manuels do not have the grounding wires?

?????

i think the 2 ground wires with metal rings on the upper intake are for the injector harness,anyone else?

i think the coil itself is stamped with +,- ,i forget the third symbol ,
look where the plug goes on.
