My diagram shows CTS pin connections:
1 blue/brown wire to cluster
2 brown/yellow wire to cluster
3 black wire to ECU T121/108
4 brown/grey wire to ECU T121/93

Check the wire colours at the ECU for 3 & 4
If you get 3 & 4 right, the other 2 wires are for 1 & 2, if you can't work out which way they go, it wouldn't matter if those 2 were reversed.
