There is a ground, with a star washer end ( external)
That goes in a hole below box and towards the valve cover. I think it goes to the head on back side of it passenger side.will look for pics later.

The ground strap attaches to the rear of the passenger side cylinder head. These pictures are of my 71 Firebird.

How many ground connections are there for ‘71 T/A? And where are the locations? Pics would be very helpful, if possible. Thank you.
