Ballast resistors in Sachse diagram for 500cc

Having started wiring up the coils through the Sachse system on my 500, I notice that in the Sachse 'simple' diagram they've got the resistors - labelled 'R' in their simple diagram going to  to the negative terminals - is that right???
In my original Alpino wiring diagram, the resistors are in the positive side of the circuit with the orange and white wiring - not the black and red....?
I don't want to fry the sachse thing - it was expensive -
At the mo I have the orange and white (live positive side) going to the + on the coils and the black and red wires from the negative on the coils going to the feeds from the ignition timing hall sensors...
Do you reckon this'll be Ok -  not having the resistors before the negative poles and is there a way of checking...?
What have others done...?
Any help appreciated...
Should've said - coils are green dyna coils - but can't see this will  change anything?
 
you have it wired correctly, orange/white wire comes from the kill switch and goes to the + coils, can continue that feed through to the positive feed into the Sachse box so the kill switch kills the coils and the ignition box
negative side of the coils goes to the sensor feed

there are no resistors required when fitting any aftermarket ignition system
