the HKS ones, almost always the ebrake wire. look under the center console for a pink wire if you have a 2002, i forgot what color for the 2003. open your arm rest, grab where the cup holder is and just pull up hard and it will clip off. it might be under the carpeting but you should be able to see the wire coming from the turbo timer going near the ebrake, just keep on following it and check the connection. i threw away my vampire clip and soldered that down. i've also done the same for a bunch of my friends who ran into the same problem.
