Am37 MB diagram of connections

Dumb question - do you have the manual?
Their website isn't much use: http://www.emachines.com/support/product_support.html?c... Series&model=T2260 only documents external connections. But you can contact their tech support.

Edit - I just reread that. I meant that my question was dumb, not yours.

There are several small plugs that attach to pins in the corner of the board, however, there are more pins on the boacd than in the plug. So it will fit several ways & I don't know which pins are to be covered & which to leave exposed. User's manual has no detail of the board.
