Ground cable?

[Bullitt]

It has been a couple of years since I took the car apart, and I thought I took a lot of pictures. I see now I should have taken alot more. I have a seperate ground cable connected to the left radiator bracket along with the harness for the fans/pump etc. It is about 170 cm long. where does it connect to? trunk light ground?
