Ground wire?

JAYNO20 · 04-24-2012, 01:25 AM

I am wiring up my aftermarket head unit and the wire harness I got doesn't have a ground wire on it... is the ground wire attached to the back of the stock radio or what?

What head unit is it? And, what brand harness? I recommend Scosche, that is very odd that the harness has no black ground wire.

Nissan usually doesn't have a ground in the harness since factory nissan radios ground through the antenna. There will be a large metal tube running behind that pocket above the radio. Ground there

He is talking about the harness that the head unit harness wires up to.

OP, there are 4 bolts surrounding the shift knob, use one of them. Never had a problem with that area.

They actually ground through the metal chassis the head unit sits in, where the screws hold the chassis in place.

when i do my stereo install i usually just use the mounting bracket where it mounts to the car . just crimp a ring connector and screw it in.

Would not grounding cause radio interference? (As if the station is going out of range)??
