I'm trying to finish installing a 2.0 L. OHC in my 1993 sunbird.  Prev. owner ripped off all elect. connections! WOW!  All I can say is giant jigsaw puzzle.  Got them all figured out, though except one.  At back of engine bay a 4 wire connector for a bolt to steel connection.  No, no not the one for the starter.  Got that done.  Ground?  Where?  Help!!!
