Thruxton R Quickshifter - Coil Question

I am in the process of fitting a Translogic Quickshifter to my Thruxton R. The kit does not plug in to the factory quickshifter harness plug under the left side cover. (?)
Instead I have a harness with connections that intercept the positive wires into the coils (located on the frame under the fuel tank).
But what I need to know is which of the blade terminals on the coils is positive. The ( open - backed )left side connection fig1. or the right side (closed backed) connection fig1. ?
can anyone help?

i know that a multimeter will show which wire has a + 12 v current if I switch the key on, but I would imagine that with the tank off, I would need to pull the fuel pump relay or fuse so as not to have a triumph BBQ.
I am also thinking I might get a fault light / code issue.
i will attach the diagram of the coil and terminals from the service manual ( RHS) and a pic of my Coil (LHS)

I have just done this on my RS. I'm colour blind so cant tell you the colour of the connection but i just reconnected the battery, turned on the ignition and used a multimeter. My shifting is quite clunky so still trying to fine tune the trigger point timing. How have you got on with yours?

The -ve posts will share a common earth (black?) whereas the +ve feed will come direct from the ECU. I would be surprised if quick shifter operation was significantly impacted by using the wrong terminal because the current is transiting the winding at light speed....
