I sent you a PM on my thouhts on the wiring conversion...here it is again for open comment and incase you havent got your mail yet..

Hia Mate,
I’m afraid I’ve been bed-ridden for a couple of days. After returning home from posting the dizzy, I came down with a bout of man-flu!! My legs are working now so I can get to PC…sweating my tits off still though (sympathy, violins)
After packing the distributor, I noticed a couple of things that I wanted to point out (that I had forgotten about when I said you could try mine)
One of the distributor cap fixing screws from an old cap has been snapped off in the distributor housing L (I used a ty-rap around the back of the stubby bit and the full cap screw to keep the seal closed) <ty-raps enclosed>
The distributor cap on that distributor is fairly worn and may need either replacing or cleaning up (fine sand paper on the flats of the HT outer contacts)
I thought as an alternative you could fit the vacuum advance and / or electronics to your distributor housing?.....but now I realise that your distributor is the points type…so the internals will most certainly be different! L…..may be the vacuum is swappable (two screws outside and a cir-clip inside).
Having said all that: If you simple want to try the ty-rap method (swap the whole dizzy) then you need one more ingredient…
-> A Condenser (capacitor)
This condenser will replace your ballast resistor (one wire that used to go to the resistor will become unused)
One wire from condenser will go to coil + and the other condenser connection will go to earth
THEN: (In answer to your question in your original mail)
The earth of the electronic distributor should still go to earth
Your coil should have two different sized terminals on it to prevent reverse polarity connections
The two wires from the electronic dizzy go to the coil terminals (one to – and one to + taking note of the ring terminal sizes against the coil terminals)
IF your coil terminals are exactly the same size, let me know and I’ll check the wiring on my motor
Hope this is of some use and not getting too complicated
If you’re struggling for a condenser give me a shout and I’ll pop one in a jiffy bag.
