Hmm...it sounds like you are dying to try it.

I bought a replacement +ve cable from Ford and that came complete with the additional small gauge wire. If I recall it disappears down into a circuit board very close to the battery area. Anyway my plan was to splice the old and new light gauge together rather than pulling the board out in case something broke. Further anyway.....I didn't do either, I cleaned up the cable that was in the car, put a new battery in and it's been fine since. The original problem was heavy crusting of the +ve terminal and cable that was down to the battery being faulty.
I'd leave well alone, these cars are bad enough as it is without tempting fate.

Yep you are just opposed to receiving good advice aren't you.
I say that you should just go for whatever you think will make you satisfied. If you have any inclination that you would be better off without the wire being connected, then go for it.
My last post on this..Take it for all it's worth and run with your imagination.

Best of luck to you sir or madam.

These folks say quite the opposite of what you said:

They say the BMS diconnect does little or NOTHING to affect car performance.

So who is right here?
