Yeh i have a manual for MM5 - its down gradeable though - mines an MM1.
I have the original but dont like using it as its quite fragile.
There are 4 wires that feed the 2 pin coils, blue, orange and 2 X white. Power for these comes through the wiper obviously and white would be voltage supply im assuming. It may be as simple as ive lost ground here but where the wires end up is a bit of a mystery at the moment.. seems to go up to behind the letter and number select switches at top
