Neurokinetick advised to scrape the traces the fets are attached to, but i have found it much easier to use 30 gauge wire and prep the wire right. strip the wire, add a little bit of solder to the wire, and while it is still hot, stick the wire to the leg of the fet where the gate is located, it should stick just fine. Neurokinectick's way works just as well, but i thought i might post this advice if you ever feel the need to return your car to normal without a trace
