Just an FYI for you traction control guys, I don't have it on the merc, but it was a PITA on the stang.

I was browsing on some mustang sites and found this adapter that wires into your system and will automatically disable traction control. It also allows you to enable it, so it is better then having it permanently turned off by a tune.

One of you might want to check if it will work with the Mercs.

EDIT: And one of the vendors may want to carry it.
