Hi, if your talking about the connector for scanner, so you can look at live engine data. Under the hood, close to computer.

You can access some codes by the mil method, you don't connect to anything. You just cycle the key, on--off, on-- off, on, then the check engine lite starts flashing, you count the flashes to get the codes. These are two digit codes. You cycle the key just till dash lites come on, no further.
