Graipner mz10 'shunt connector'

I finally found the best way to bind the Graypner receiver to the MZ-10 via a YouTube video. So that's progress.

What I'm faced with now is the need to REVERSE the response on the servo. The manual suggests this could be done by using a shunt connector that was not included in the package. There are only three pins in the back (while the manual show 6.) Does anyone know what the shunt is? Shorting pin one to two, one to three,?

Alternatively, any suggestions about where I could buy said connector?
Thanks. Bulky4
