Well, you can relax a lil bit, since the switchbacks are actual bulbs, that pop right into your existing sockets. Only wiring (possibly) would be adding load resistors. A plug and play alternative to that, is replacing the flasher module which is just above and to the left of the brake pedal, with an LED flasher module. I went with the module swap, took about 5 minutes. Hardest part was contorting the right way to be able to look upwards under the dash from the floor. For someone vertically challenged, it might be a lil easier
