One of the really cool things about this wiring harness (the $150 lower cost solution) is that they provide the system WITH turn signals. Very nice. They use a dual filament park light mod for the front park lights, and no mods on the rear which have two bulbs already. The downside is a 7 wire turn signal system. But I just paid $42 for the good switch system and that is a small price to pay to do it so cleanly.
