4.8?

Hi Guys

Would like some sort of diagnostics for my 4.8 but can't find any info on what's available for my 2003 4.8? I can't even find a port! In the place where the port is on my 1998 2.8 there is a little box with a red light on it in the 4.8. Anybody know what that is?

Thanks

Nick

Should be under the dash, slightly to the right of the steering column, it kind of faces in a downward direction.
