Te27 Speedo Cluster Wiring

So I'm thinking of swapping my te27 cluster into my ke25. Parrot sent me a diagram of the pin plug into the back of the cluster. According to it I just have to rotate the plug and plug it in and run a black wire from the negative side of the coil to pin 7 of the plug

I have read alot of different things and people say u need to swap wires etc. I had a look at a few looms I have at home. One loom I have even has pin 7 (black wire) in it amd near where it hooks to the coil it has a black wire red trace taped away with a round terminal head. I suspect this is a te27 wiring loom I have. I have another loom with totally different color wires in the pin plug compared to that of my suspect te27 loom and compared to the diagram pete sent me.

Question is has anyone done the swap into a ke25. I'm interested to know what you did. And I'm interested to hear from someone who has done the swap into a ke20.

I have a funny feeling that ke20 and ke25 have different coloured dash cluster pins

Can anyone confirm my suspicions
