Which SLOT on base for Glad NXT EVO Omni Throttle

[flyty]

Hi I've purchased Glad NXT EVO stick and Glad NXT EVO Omni Throttle.

1 There are two sockets/slots on the BASE motherborad (its different to the setup video on youtube) they both fit the stick plug, I used the one labled STICK for the STICK.

Is this the correct slot for the stick?

2 For the left hand throttle I used the second SLOT named EXT? (I couldn't read it cleary)

Is this the correct SLOT for the left NXT EVO Throttle?

I havent plugged them in yet as don't want to break anything.

Thanks in advance.
