Mobelec Electronic Ignition

[Windsor]

Can anyone help with a wiring diagram/instructions for a 1970s Mobelec ignition kit. Its to suit a Ford 1600 xflow (711m) in my Morgan. It came with the car. but was not wired up, & I would like to try it. I have a 'box', with a short black lead (presumably an earth), a long red, long yellow, and long green leads, and the sensor lead and sensor, which goes in place of the points. There is also a separate 'tacho unit', with a yellow and a green lead.
Any help will be welcomed.

Many Thanks,
Any sign of a connection to your tachometer, or is it a mechanical one?
