1. Use a paper clip shaped into a U to ground the pins.
2. The DLC socket is located under the dash, about where the steering wheel is.
3. The picture in the previous post is rotated 90 degrees to the left. 'Up' is to the left.
4. Thanks go to BigRig for the original post, and to #1Son for archiving the links on his site.
