Ok so i have my hands on this Dual WIng spoiler off a merkur, it has a rear windshield wiper, only car ive seen with this wing was Cosworth_wannabe and like ive said before it kicks ass, i just need to know how to install it onto my 1990 scort, and what wiring do i need to do to use the rear wiper, i really want this bad mutha sucka on my ride, once this is up there i´m gonna put my audio system in.
