96 OBD 2 translator computer # ? ( car side )

When looking at some wiring diagrams for a R129 SL , I came across what looks like a translator box that takes info from sensors / engine computer and converts signals to a OBD2 output.

It looks to be 96 only work around and is not the California blinking red led in the diagnostic connector.

Anyone have a part number for this box?

My 97 SL320 M104 uses a Bosch ME2.1 and does not have such a box, and the 96 would still be using the old style VDO / Siemens type engine computer and about the time OBD2 was being phased in.

More info

The translator is called N59/1 Diagonstic Module OBD 2 . It only looks to be used with the 96 M104 HFM-SFI. I only have R129 wiring manuals so no idea if other cars are the same.

When looking at the mixture formulation wiring diagram, only 4 wires are shown leading to the N59/1, the block shows that there is more of the N59/1 somewhere but I haven't found the 2nd diagram.

Wires from the engine computer to N59/1.
