thanks Nino, but I'm a little confused here. in this particular case I have a single wire that originally connected to the lug and I had two blue wires that connected to the frame as did the braid. so do I connect the single coloured wire to the bottom or top lug and what the braid to the frame, and the 2 blues wires?????

Two blue wires are soldered to the bracket - exactly as original. I've done it here on the Eight Ball - check the Blue and Red wires ;
