1972 TH400 firewall hole location for harness?

Does anyone have the exact location for where the TH400 harness goes through the firewall?

You should have several dimples in the firewall between the big black plastic bulkhead connector and your emergency brake cable. I believe the TH400 cable passed through a hole located at the dimple second from the top.
