NB Mk 2 mk2.5 headlight change

Ok then, having stacked the front end of the MX on a track day I’ve now fitted a mk2.5 to the front of my mk2.

 

All fitted fine,but having converted the headlights by changing the loom,the headlight levelling doesn’t work.

 

It worked with the mk2 headlights, I’ve checked fuses, all OK,and double checked the wiring mods against the Haynes wiring diagrams that I have and all OK.

 

I have power and earth at the pins as expected.

 

Any ideas?  Do I also need to change the internal switch on the dash, is it as simple as that?

 

Is there a way to check the levelling motors on the headlamp units themselves. ?
