Most shark wiper motors have a clip on the frame that goes to a black grounding wire, which winds up on the starter area of the engine block, it's a ~10 ga black wire with a 3/8 loop on the end, and so is typically hooked to the battery post by mistake, so the wiper and heater motors are now hot on the frame at all times....
at any rate, I pulled MY black wire up top and found a handy spot on the intake so as never make THAT mistake again....
