As I've mentioned in the past, I like to keep things simple, and I'm no electrician either. So all I did was remove the cover of the fuse box on the drivers side, located the spoiler motor fuse, and pull it out.
I then cut the fuse right down the middle, separating the left prong from the right prong. I removed all the translucent plastic from them and at the top of each prong there is a small hole that I attached 1/2 of an old 2 prong light cords copper wire to. I attached the other wire to the other prong and wrapped both with electrical tape. I then reinstalled the two separated prongs back where the existing fuse use to be. Since it was a flat light cord it had a groove running down the middle of it so it split apart quite easily so I had enough slack to run the wire under both sides of the lid of the fuse box when I put it back on.
I ran the wire past the hood hinge, thru the gap in the fender and right under the fuse cover on the side of the dashboard (just to hold it out of the way) then I tucked it into the gap where the kick panel meets the bottom of the dash. The wire now runs under my floor mat where it exits at the left rear corner of the mat where I have an inexpensive "on/off button switch that allows me to deactivate the spoiler, until I decide I want to put it up.
The whole set up was temporary as I didn't know if I would use it that much or not. As it turns out, most of my highway driving is between 70 and 75 on dry pavement so I don't feel I'm taking any unrealistic chances with loss of traction at that speed due to less down force by not having my wing deployed.
I like the way the car looks both ways, but most of the time I prefer to cruise with the spoiler down. Besides, it's fun to be running 70mph and have some guy come up behind you when they feel you're not completing your pass fast enough, then in mid pass activate the wing, downshift, and hit warp drive.
So far, most guys don't even try to stay with me. I think it sort of phycs em out.
When I eventually get my "dimmer switch" control installed, I'll naturally run the wire thru one of the grommets in the fire wall.
