My wiring on my 70 el could stand to be updated. There seems to be a short, i'm told. On any given day the problem seems to come and go, the tach needle jumps all around, the shift lite goes on and off, and while this is taking place , the car won't shut off, it seems to run on like its diesaling. I have to turn off the fuel pump to starve it out! got any ideas?

sorry wrong location!!!
