Here's a shot of the area around slot 7. The cable (with single-pin-socket) attached to the card would reach to the connectors to the right of the slot but I've no idea which connector it should go onto (There doesn't appear to be a single pin, just a dual connector above the sky-blue pot and a quad between c13 & c14.
I'd be grateful if you could dig through your docs to find a possible answer.
