I am installing some new LED's, Ring of Fire, Radiator Grill, Big Bike Lighted Saddlebag and trunk Trim, LED light stripe under saddlebags. I am going to pick up 12 vdc at the accessory panel on the fuse block (correct?). The question is where is the best place to pick up thr ground? The battery ground (negative terminal) or where? Thanks for your help.
