Hi,

I attached the pin-out below for both connectors. The first five are specific to C1 and the remaining pics are C2.

To make everything readable, I had to cut the pages and enlarge them. So, the legends are a few pages long.

Let me know if this helps or if you have other questions.

Take care,

Joe
