HAIN Diagnostic Connector Cable Compatible for Mercedes Benz Vehicle 38Pin to 16Pin OBD II Diagnostic Adapter, Car Transfer Line, Automobile Diagnostic Lin

These are much cheaper than Mercedes OEM and I am happy to report that they work perfectly for connecting a modern OBDII scanner via the round OBD port on older Mercedes cars and trucks.

Worthless. Only 3 wires crossover. From Mercedes 38-pin connector pins (1), (3), and (4) become OBD2 pins (4 & 5), (9), and (2) respectively. No new information. I can get that data from the car’s OBD2 port.

Great product. Needing it to hook up my OBD2 LAUNCH scanner.. so thank you

Bought to use on Mercedes. It didn’t work because the scan tool required their own model. Check vehicle compatibility because these round pin connectors aren’t necessarily universal.

Purchased this item to check OBDll codes on a 2002 Mercedes E55 AMG. It was shipped promptly and fit as expected. Great price, well made and no problems .

The cable is well made. However, there are very little scanner that could use these cable for Benz before 2002.

Got this with hopes of being able to read and reset the SRS on my Mercedes knowing that the 38 pin under the hood is the only way to access that code. I tried this with my reader and it could not access any more outputs than already available on the under dash OBD2 port. This is only useful if you have the 38 pin and do not have an OBD2.

My check engine light came on and ordered the connector to conduct a reading. I was impressed by the ease of use.
