No such thing. You should only have the one wire from your coil to the distributor.

There is a small braided ground wire from the dist body to the plate on which the points are attatched.
Is this what you mean? Jeff 911T |

Since we have no clue what year car is being referenced here ... it is hard to say for sure!
But, all '69 - '77 Bosch CDI installations had a ground braid strap/shield that ran from the CDI-unit to distributor body, and also to the coil! The schematic section below clearly shows the brained ground straps:

maybe that is why the wire is not connected? |

Hi,
I have a mystery ground wire and this post basically described, but I still can't tell where the wire is supposed to connect. Here is a picture. Can someone tell me where it is supposed to connect to? Is it possible that I cut that wire when I installed the Pertronix? I don't remember.  Thanks!

Neil,
The ground strap originally had a large 'ring' style terminal lug [and a oversize M8 flat washer fit under it] on the stud that clamped the distributor body in place.
