Arducopter 2.8 connector types

[baronpork]

I recently came into posession of APM on S500 frame.
Board is Arducopter 2.8, with external MAG/GPS.
Wanted to connect bluetooth module to telemetry port only to find out i dont have suitable connector for it. It looked a little like JST SH (1mm pitch), but aparently its too small. 1.25mm ?
It is identical to I2C connector but 5pin. What is the name/model of this connector ?

There';s nothing i could find in APM wiki regarding this ?

Also, Telem/I2C port pinouts would be good to have.

Muchly thanks...
