A few days ago I had a problem with my car that I thought was the transmission. Turns out it wasnt, but Im wanting to know what this could be. This little connector was arcing from the coil pack to there, with a HUGE mini lightning bolt. When it would do this the car would buck really hard and peg the tach to zero. I taped it off, but it still does it from time to time, and sometimes it kills my tach completely. What is it? Also, in the 2nd picture, what is this little jumper plug? And in the 3rd, what was originally connected to this bolt on the SC top?
