I just acquired a 1992 400E and the SRS light is on. I want to read the codes but can't find the location of the X92 diagnosis port to read off the codes. Per the service manual, the port should be located under the hood just in front of the fire wall - see attached image.

Is it located inside the box that's in front of the fire wall or some other place?

Thanks,

HS
