Hi ! I'm from Poland
I tried install gauges from ST to TDCI. Unfortunately, gauges doesn't work. Works only oil pressure.
Turbo and oil temperature doesn't work Mayby TDCI doesn't have map sensor and oil pressure sensor.
Here you have a connection :
1,2 - battery 12V
3 - ground
4 - ignition 12V
5 - can - ( pin 17 in main gauges / cable color : blue/red )
6 - can + ( pin 18 in main gauges / cable color : gray/red )
7 - ilumination - battery 12V
Sorry for my english.
