Rear Amp issues with Rear speakers and A2B connector

[radioactive]

Hey guys, May be some one can help.
My rear speakers and Microphone stopped working - Meaning they go on and off with clicking noise. I took it to SC and they said we have to replace the amplifier. Since I am out of warrantee , I decided to do it myself. I bought a working amplifier from ebay and replaced it . Still same issue. The on and off rear speakers and clicking noise. I was troubleshooting the situation. There are three connections to the amplifier
1 small white , 1 small black (A2B) and a big white connections goes into the amplifier. when I connect all three the light inside the amplifier blinks amber and every time it blinks the click and disconnect is happening. Now I take the black (A2B) connector off, The blinking amber light is off and no clicking noise but rear speakers not working. Microphone works. I guess that black one is rear speaker connections.
Any pointer from folks here, What else I can troubleshoot?
How do I remove the A2B connector and put a new one? Is there a wiring harness? I did not find it in tesla parts site

Hello I'm having the same issue, I think the problem really came from MCU cause I have checked the circuit from MCU to the overhead console, and from overhead console the amp, the circuit is OK no shorts or electric noise, I have tested with toolbox and the test for amp and Lin connection failed I think you connection is not the issue and the issue came from MCU

Is it possible to replace a rear amp from another model 3 without coding it?
