Today I finished installation of FBHC, no issues with that part. Controller is paired with my phone and when message "ON" was sent, controller came back with an error message

Cmd:ON (15:46)
Comms err
FBH:Off
Ambient
Status 00/0
Volts 0
14:46

I suppose that I have a problem with green wire (communication) but I need confirmation for that and suggestion from FBH gurus what to do next.

Problem found but nor fixed, because I have another problem now.
A friend of mine was helping me during installation and I remember that he said that he will remove rubber plug from connector while I was looking for few ties to fix cables. He even put pin in place so I was sure that was it.
Today I found some time to investigate a problem and I was p***** off when I saw that green wire was in pin 3 instead 2.
What and idiot I was not to checking thing after him!!

Any idea how can I pull off that bloody pin out?
