Suggest that when you add turn signals, do not butcher up the original wiring. You can purchase 4 wire bundle of wires like used for trailer lights then use this color code for each of the turn signals. You can purchase lights that will fit between the bumpers so do not change wiring. Used a multi connector from Radio Shack to connect wires from the turn signal unit to the lights, turn signal relay, power and ground. Easy to remove if required. Placed a strip of tape around steering column to prevent scratching the column. Installed a good ground wire from the turn signal unit to chassis ground. Hooked the rear turn signals into the brake system so have 4 lights on the rear when stopping and three red lights plus a turn signal light when slowing and turning. Want as much light as possible to get peoples attention so do not get run over. You have to drive defensivley
