Been tested and verified a long time ago... you can search for 'traction control fuse' or 'disabling ESP' and you will find the threads.

Only real way to disable the ESP is to have it disabled in the ECU/PCM. Another option is a little box that Woody made to 'fake' the signal from the inertial sensors. This fools the ESP to think that you are driving in a straight line and not going sideways (I think that's what I understood).

Good luck!

EDIT: I just noticed HDDP's post above. Please refer to either HDDP or Woody for the bible on ESP/TC disabling.
