Imaging problem using the Gemini System

Hi everyone,
I have recently upgraded my Losmandy C11 with a Gemini Goto system. While everything is going well in that department I'm finding that when imaging in 'Photomode' using CCDops with a SBIG ST2000 stars look slightly elongated after about 1minute of exposure. It's not a polar alignment issue as that's already been done with a polar alignment scope and the main scope working at f6.3 is balanced.
On re-reading the manual I have gone back to the box and discovered a component that was not attached (see images) that I'm thinking may be a "tracking interface cable"???.
If it is should this part be attached to the CCD connecter which in turn will send corrections to the drive to offset drift of 10 pixels + ?

I would appreciate any constructive advice you can give.
