Probably the harness used to read you CEL's- they plug into each other and the CEL code is displayed.

If you're talking about the green connectors, leave them unconnected. They are used by the factory during shipment and disconnected at the dealership. I don't remember what they're for, but do not reconnect them. If you're talking about the single connecter with a trapezoidal connector, that is the OBD-II connection. You need an OBD-II scanner to read the codes. Connecting the 2 green connectors will not do anything.

Connecting the green ones together will put the ECU into a diagnostic mode where various relays and solenoids will cycle (you'll notice the fans going on and off) and the CEL will flash continously.
There have been numerous instances where people posted that they suddenly had these "symptoms" and wanted to know what was wrong with their car, and it always turned out that they or someone else had just been working under the dash and saw those connectors hanging loose and plugged them together.
