Hi, i'll guess yours is 12 volt battery ignition, except you mention connecting to the stator which make me wonder if you have a flywheel magneto model 'as i have'.
The original coil for the AT1 magneto & the AT1 12 volt look the same in shape & size except the magneto coil will have only one wire to get its voltage from the mag.
The battery ignition 12v has two wires, one to the points & other to/from the battery in a round about way via the switch.
So first off which one is yours?.
If you mean you're buying a coil with no wire to the spark plug then i guess wire can be bought from an auto store but really the coil should come complete if new.
Here's a pic of my 12 volt ones i'm selling but i'm in NZ so not viable to buy from me. Hope the link works to view.
Mine are off something like RD350 but same 12 volt coil except the red/white battery wire might be red on yours & seperate wires not multi wire plug.
Mine don't have plug leads, got lost like most things around here lol.
But under the screw cap should be a rubber seal to slide over the plug lead then push the new lead hard onto the sharp spike down in there, then screw the cap on with the seal.
Hope i've not overly confused things.

Even ran one of those coils on my Lada Niva haha & worked perfect.
