Retrofitting outside temperature sensor (5pin) C124 1988 300CE
 

Hi everyone!

I'm currently retrofitting outside temperature sensor in my 1988 300CE. I got a complete set from 1994 coupe, so it's newer 5 pin version. I got all wiring sorted out, except the hall sensor connection.
Back of my instrument cluster has these hall sensor connections:

I have original connector (black) that comes from dash to cluster and now somehow i need to connect additional hall sensor wire (green) which comes from temperature display into that plug. Maybe you have any ideas how should i do that? Maybe there was multiple pin connector available?

Thanks in advance!
