So if as long i don't power to this line, i should be fine

example : on the eps connecter i added a 3v to 1,2,3 or 4

I may be wrong.

Powering ground is always a bad idea. 

Just look at the connector you have Vcc and the com pins. So those can only be ground (common) otherwise you don't have a closed loop.

What us Vcc?

I may be wrong.
