OK, now I'm stumped. I've read here after searching that my car should have onboard diagnostics in the form of that little box with the LED. I've been looking for it all over the area of the battery, and I'm at a loss. I'm beginning to think that mine is MIA. Attached are pics of the area; if anyone notices anything I'm missing, please let me know. I do see an 8 pins recepticle that I'm thinking might be my solution (with a scanner). Please let me know if my thinking is correct. Also, there seems to be a ground strap or something unhooked (also in the pics); I'm assuming that this should simply be grounded out, right? Thank you in advance.
