It tells you in the program book how to ID the pin.
Its all software.
Good luck!

Subject: [Repeater-Builder] TKR-850 - Where to get CTCSS enable signal?
> In the course of connecting my new TKR-850 to my Arcom RC210
> controller I found out that the repeater's "Squelch Control" ouput is
> not actually a CTCSS squelch signal, it is a COS signal only. In
> other words, the "SC" pin goes from 5v to 0v whenever ANY signal is
> on the receiver channel, whether or not it has the right CTCSS with
> it. The CTCSS is enabled for the channel in the programming (173.8),
> but it only cuts off the audio. The CTCSS enable is not reflected on
> the repeater's SC pin. When I change to the wrong CTCSS code on my
> handheld, the receiver speaker is quiet, and no audio gets to the
> controller, but the "busy" light on the front lights and the SC pin
> goes to 0v.
