This is going to be a rough and ready writeup of electronic ignition kit installation.
The distributor, don't worry if your dizzy doesn't look like this, most are Delco, this is Bosch.
The complete kit, tiny little things:
Some useful items, pre-loved pink pyjamas, not so essential some thinners to clean away old oil and grease:
Dizzy opened rotor-arm off:
Points out, baseplate exposed:
Remove the condenser too, and any associated wiring, clean up the baseplate with clean rag/solvent
Keep the old condenser and points clean, dry and available for replacement if ever desired.
Trial fit the sensor unit, route the cables round the outside of distributor, away from moving parts:
Looks good; sparingly coat underside of sensor unit plate with heat conductive paste (provided), and seat the unit on the little locating dimple and refit with the screw that formerly held the points down:
Next part is the kit's little hollow ring, its shaped to match the lobes on distributor shaft, rotate to locate it and push it down, pop the rotor arm back on top, replace and clip on the distributor cap:
Two little round terminal to spade terminal connectors were provided with kit, I'm using one to make an extra connection on coil thats come through the ballast resisitor but will like the coil get the full 12v for starting. This isn't the best recommended method but allows use of the existing coil-ballast setup:
Hookup the red wire of pickup sensor to extra new connection on positive + side of coil, the black wire to the negative side of coil that the points used to connect to:
And that's it done; it's a good idea to check and set the static timing if necessary, with a strobe light, some chalk or a crayon is useful to mark the crank pulley pointer to make it stand out under the strobe light:
