I'm installing the JB3 and when I finished, I hit the start button and the car cranked for a long time, and then just stopped....the car was giving me all these codes, and now when I hit the start button to try again, it won't crank at all. I did all the steps just like the directions said; however, I don't understand what they mean when they say..."plug the JB3 box in to the harness"

I also see in the pdf on step 11 that I have to "insert the JB2 harness large black connector in to the JB3 box, and tighten screws....Not connecting the actual JB3 computer to the harness is the most common installation mistake made. I don't know what they mean by "box"... I just got a wiring harness.

Any suggestions?? I need my car for work tomorrow! Thanks.
