This has been exhausted, but here goes:
On your manual (SVT)
You'll need to use another spot besides the one that ATX owners are privy to (the empty cluth grommet)
You'll have to do the following:
Run the wire from the battery to the driver's firewall, through a rubber grommet at the extreme drivers edge of the firewall in to the area underneath the wiper cowl (plastic cover.
Remove the wipers, and the wiper cowl, then look roughly 9-12 inches towards the center of the car and there will be another rubber grommet that leads in to the upper driver's side floorboard area (just left of the brake/clutch area, and higher than visable.
works best to stick a coat hanger through from the cowl and then look in the floorboard for the "bulge" in the carpetting, and use an X-acto knife to cut an "x" at that location, then fish the wire through with said hanger.
running the wire in the steering wheels' grommet would likely lead to EXRTREME wear, as well as possible danger (get that wire rubbed through from eventually contacting the steering column and then have a short.. not S.M.R.T.)
