Purpose of Wires 6G and 7G?

[HoveringHMMWV]

I am in the process of determining the purpose of a few cut, missing, and damaged wires in and around my battery compartment. The 6G wire was easy enough from reviewing the electrical diagram and the terminal board is still installed with fuses.. But I have not been able to locate the "ground strap" for the 7G wire. From the 7G wire's length, the ground strap should be located near the 24v terminal board but I believe it to be missing. Also, would the ground strap and 24V terminal board be a part of the automatic fire suppression system and/or heated windshield?

the Transmissio/accessories panal behind the battery box is for all additional 12 and 24v accessories such as Cig lighter adapter, AFES, deicer module etc…
