Im cornfused about what you had to begin with when points were used???????
Id expect a single SWITCHED wire down from the dash Ignition switch which was, or course, hot ONLY when the ignition was on, i.e. its SWITCHED and its connected to the high input (NOT distributor) side of the igntion coil.
Id expect a single wire on the coils other side wired to the distributor.
NOWWWWWWWW in the event the tractor was 12 volts but used a 6 volt coil, it may have been equipped with a start by pass circuit consisitng of an extra third wire BUT such a wire would connect to EITHER the coils high input side (i.e. 2 wires on coils input not just 1) or the low output side of a ballast resistor.....
NEXT a normal electronic switch set up would only need 2 wires. One (say red) wires to the high input side of the coil, the same place where the switched wire down from the ignition switch connects.........The other (say black or white) wires to the low output side of the coil.
Those three wires have me cornfuzeddddddddddd
MAKE SURE YOUR ELEC SWITCH MATCHES THE TRACTOR POLARITY (pos or neg ground) or you may fry it and to get the most bang for the buck and utilize all the advanatges that elec switch has to offer ID MATCH IT WITH A HIGH ENERGY HIGH VOLTAGE COIL and run a wider plug gap if it were me.....
PS go with that the vendor says, not myslef or others here, cuz youre dealing with an expensive switch and I dont wanan see you fry it cuz we told you wrong

The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to. In such cases, rework makes what could have been a fun project turn into an irritant or even a nightmare. Minor Irritants To give you an example of an minor but irritating proble
