Bracket Vital?

Honestly I am unsure of the fastening location on a 74 Commando. Cannot find it's location in my tear-down photos and the thread I saved that LAB helped out with lost the image he put up.
I am assuming this is routing for an electrical line?
Your help is appreciated.View media item 128
