Lambda Sensor Wiring, Which Is Which!?

[welshpug 1,657]

here goes, I have a gti6 plug, which I can check the wiring diagrams to confirm the funcions of each pin of the 4 wire plug, however I dont have the original Sensor, I do however have an S16 sensor, which originally had 2 separate 2 pion plugs, which I;ve managed to extrace the pins from.

 

but here's the snag, I forgot to mark which wire came from where!! DOH! so I dont know which of the 2 white, oen grey and one black goes where in the gti6 loom, can anyone help??

2 white wires normally go to the heater, one +ve the other to earth. Grey and black normally connect to the green and red signal wires back to the ECU.

From an MM8P loom so might not be the same colours but its green to pin 1 black & red pin 2 white on white plug & pink to white pin 1 & green to white pin 2 on the red plug (earth) (number on sensor plugs).
