So from largest diameter to smallest diameter we have:

1) Heater -/ Thermocouple- (GREEN)
2) Heater +                           (BLUE)
3) Thermocouple +              (RED)

Is this accurate?

Thank you very much for the connector pinout!

No,

Shell (Green) -> Thermocouple B
Sleeve (Blue) -> Heater +
Core (Red) -> Thermocouple A and Heater -

Hmmm, this video and some other diagrams I have seen online seem to indicate that the correct pinout is:

Outer/Green: Heater-/TC-
Middle/Blue: Heater +
Inner/Red: TC+

I may just wait till my cartridge arrives and measure for myself. I don't know why there is so much conflicting information about this...

Greatscott didn't check the core to sleeve resistance (also 0R), otherwise he might have realized he is actually passing current through the TC junction.

I've attached a cutaway of a 245 cartridge that should make things clear.

Also here is the connection direections from sparkybg:

3. JBC C245:
 - Outer shell (green wire) connected to (mains)EARTH and SENSEB
 - Heater positive(red wire) connected to Vout1- and SENSEA
 - Heater negative(blue wire) connected to Vout1+
 - 150ohm between ID and Vout1-
 - 5.6k between ID and Vout2-
