At times when I have worked on these boards in amp I have ran a ground wire from the molex connector trace back to the common of the rail filters so I don't have to have the molex plugged in.
When I have done this I have never noticed a increase or decrease in 120 hum / noise level in the amps output so I remove the wire when I am done.
