Hi, Own a 1995 420 S class looking for obd 2 port, looked under dash below steering wheel removed the black pastic panel with insulation and can not locate it?

obd 2
 

obd2 wasn't used until model year 1996

O B D
 

What is the 1995 version, what else to check for the check engine codes?
Thank you!

Captain

you will need to use the 32 pin connector inder the hood, that port is not compatible with obd 2 code readers, are you near san diego?

32 Pin
 

Where is the 32 pin connector port located under the hood?

it is on the passenger side under the hood, it is under a round cober by the hood hinge

I think you're going to need a mushroom.

...and it is 38 pin, not 32.

Look here for location;

And Jims excellent page for more info on it;

Remember that the electronics changed quite alot
on the W140 thru those years, and that what someone
has, maybe you don´t.

And to get this correct, here are a russian page with most of the
wiring diagrams for your car;
