The ground wire can be checked to see if it grounding.

AKA checked for continutity to a ground path.

1. place a test lead from a multi-meter , (you probably should have a multi meter , if not, ---get one , something basic under 50$)

----set to test resistance to the proposed brown ground wire on one end, -- and touch the other end to a known good ground , on an SPF the aluminum firewall is a good test spot. or bare metal on the engine block.

your multi meter should read 0.00 resistance. (closed circuit) , if it does --the brown ground wire is infact...ground.

--if not ( if it reads infinite resistance (open).) then yes, add the wire to ground it to the frame.

if you need to ground -- remember you will need to have metal to metal contact (no paint)

--UPDATE 8-27...

I checked and the Ground wire on the VR as located on the fender-well. It is a direct wire from the brown alternator pigtail lead. This means in order to be (have a ) good ground at the VR both ends need to be hooked up.
