Recognize this Electronic Distributor unit?

Had this on one of my Fiats once but I think it leaked oil inside. Was going to give it a go again but cant remember how it hooks up or who made it. Has Red, Black and Purple wires:

That is the old Allison XR700 unit that is now sold by Crane.

It is an optical system, an LED points down towards the sensor, the plastic wheel on the shaft blocks the light from the LED and the slots in it allow light through to the sensor which the control box then switches the coil to fire. The spark proceeds in the normal fashion to the rotor to the plugs in the normal fashion. This is a good system when new and is all solid state, you do need to use a non resistor coil however as I recall.

I thought it was an allison but couldnt find one that looked like this anywhere. Need to know what wire went where...

Dont flame me if it blows up, but this would be my guess.

black wire to ground
red wire to 12V power
purple wire to coil negative terminal

Thanks for the model # and seems that the Allison XR700 Purple wire goes to Ground as found on a triumph forum post. Would make sense as I think it had a larger terminal. So Black to coil neg, red to coil positive and purple to ground. I may give it a go or atleast I can sell it and tell them how its hooked up. Thanks everyone!
