Hello everyone.

I am trying to replace the stock unit with an aftermarket. When I pulled out the stock unit I saw two plugs in the back.



Can anyone tell me what the white connector with the black center is? There are two black wires coming out of the back of the plug, so I thought at first it must be the ground, but the wiring kit I bought has a black ground wire that wires into the larger multi-wire plug.

Can someone shed some light on this for me?
Thanks,
Michael
