What are these wires? (M20/Motronic)

On the engine loom to car loom connector what do these pins do? :

8 yellow with white stripe
9 black
14 blue with yellow stripe
15 black with green stripe

I've figured the rest out from a diagram but those are not labelled

not sure if this will help but for the diagnostic plug

pin 8 white/green
DME Control/Idle control
pin 9 black
tachometer
pin 14 black/white
obc speedo signal
pin 15 black/green
Strarter/unload relay

i realise the colours are not all the same but i hope you can trace the wires and solve on or two!!!

Try this

8 = DME Cont/Idle Control
9 = Tachometer
14 = Speedometer Signal(OBC)
15 = Starter/Unloader Relay
