Thanks for the reply.
Indeed I did not understand the instructions properly.
But now I have followed the instructions as you can see from the pictures.
However, another problem presents itself.
I can't start the engines with this hardware connected.
Without the hardware the engines start as normal.
This has to do with the settings of detent or no detent. Unfortunately I am not a techie to understand this.
I have tried to set the Hardware Power Detent Ratio correctly. I can't figure it out.
There is no Switch on this throttle to set it to Reverse. It is simply pushing the lever down through the zero-level.
Thanks again for your thoughts.
