Okay just received the Hot Rails bridge for strat. It costs 50 dollars to get a tech to install pick-ups now..........and i dont have the money (sadly) to get it done. Well,.i wondering if you guys would help me and give instructions of how to do it.(or if its too complicated i will save up). But i get the diagram and know the volume, and tone and all that....but i dont know what "ground wiring means". lol if anyone can help..thanx..but if its too hard i will take it to a tech.
