We are installing a 225 amp service Off an existing pass through meter. There is a small braided wire running down into the ground that looks like it was installed from the power company. There is #6 from neutral lug to the braided wire. Would that be considered my MBJ or would I still need to make that connection at the first means? Can someone explain why or why not? I'm finding mixed answers every where I look.

There is no separate grounding conductor ahead of the enclosure that contains the main disconnect.
as in if it were to be N and G bonded in meter i would have to have a seperate grounding conductor from meter to disco? Sorry I'm still wrapping my head around Grounding and bonding

No, and no problem.
Ahead of the service main, all bonding of non-current-carrying metallic is directly to the neutral.
Any service conduits, raceways, enclosures, etc., are seen as part of the neutral conductor itself.
That's why the neutral conductor, as well as grounding electrode conductors, etc., may be bare.
All of that metal effectively (re-)defines the grounded/earthed, zero-volts point of the service.
A separate conductor connected to the neutral in more than one place forma a parallel path.
What the power company does on their side of the meter is basically "none of our business."
And, the NEC views the meter as a "lump in the service cable." (Mostly applies to residential.)
