Positive to Neagative - graound that is.

[Trevor Triumph]

I have a 1966 Spitfire that was positive ground. I remember there is a procedure to change it to negative ground. As I recall there was one wire to touch to a terminal on the control box. The last time I did that was about 1993 and a friend did it for me, so I didn't pay close attention. I cannot get my memory to go back that far. Any suggestions? T.T.

Thanks so much. That means the car is so much closer to running! T.T.
