Usually refers to a ground wire which is either bolted to the frame of the car (there are several), or bolted onto the engine at the left rear above the oil filter. There are several ground wires/cables throughout the car, there is a picture in the FSM that shows where the frame ground points are - look in the index to find it.

I saw that in the fsm pg 197 but its vague, just shows a grey dot on the harness. I was looking for an exact mounting location.

For an '85 Circuit 450 references directly to G103 which is on engine vicinity of alternator.
