I have a sony wx-gt77ui head unit and wire harness adapter. The head unit has the ground wire with a connector on the end of it so you can screw it directly the frame of the car.
My wire harness adapter also has a ground wire in place.
Do I cut off the connector and ground through the wire harness or do I use the head unit connector and just screw the wire connector to the car.
Does it matter either way?
Thanks in advance folks.

It's more or less installer preference:
I've never really heard advantages either way, but there was a recent thread where the factory wire worked and the bolt behind the dash did not.
Hope This Helps!!!
Anyone else have suggestions?

I have always just tapped the HU harness into the factory ground. I know that around my deck there are no solid grounds without lengthening the wire and you want it as short as possible. The factory decks wiring harness has already done the work for you and is more or less connected to a ground that will suffice.
