you mean the ground wire?
well, take it from the volume pot and stick it thru the hole and up into the trem cavity. then just slide it into one of the screw holes and you are done.
its pretty simple if its just a grounding thing, but im not really sure what you mean.
EDIT: I just read your other topic.
where do you live, and when did you buy your jag?
was it new or used and what time era is it from?
