It's nice to receive a product that does exactly as you expect. No surprises. No issues. Unbolt theoriginal, Bolt up the new one. Crimp on the female bullet connectors to the original wiring and hook it up. Really nicely made and the powder coat finish is excellent. Neatens up the rear a treat too, of course. Comes with number plate extenders which were required to save lining and drilling extra holes in the plate. So there's nothing required for the install, at all. Great stuff. Highly recommended if you want to make you WRX or R less dorky lookin' Cheers Josh.
