Hi all, new the board. Just picked up a zizzle toy pinball game for the kids, but have to admit it's pretty fun once I installed aftermarket buttons for the flippers. I'm looking to replace a burn out blue LED on the playing field. I have the LEDs mentioned about in this post, but I'm a little weary to start cutting wires as it's all daisy chained and i don't really know what I'm doing. I can solder a little bit, cut and stripe wires, insulated with hot glue...but which wires to cut, use the existing platform the current led is mounted to, etc...which is the ground? why are there four wires? (2 for led and 1 for ground no? )just don't know. Here are a couple pics. If anyone can help me with some tips I'd appreciate it big time! Thanks much.
