Hello. I own a 2001 Maxima GLE. I tried to replace factory stereo with aftermarket Single Din Bluetooth stereo. I have a wiring harness that plugs into factory harness. My stereo has 3 plugs, but my new replacement harness only has 2. Factory stereo has the factory Bose system. I need to know what harness I need to plug into my factory harness. I have seen some that “fit” my vehicle but have 4 RCA plugs. My new aftermarket only has 2 RCA outputs. Any advice? Thanks in advance.

Isn't it for steering wheel controls? I just use the standard harness and it works (never used the wheel controls in my life).

 

what does the radio manufacturer say the "extra" connector and the 2 rca connectors are for? The owners manual will tell you. Not enough info here.
