1985 M117 Jetronic wiring schematic
Does anyone have a schematic for the pin-outs on the Jetronic control computer mounted inside the cab on a 1985 500SEL?
I'm looking for the O2 sensor wire pin. |

Never mind. Using my trusty multimeter I discovered either the O2 sensor doesn't run to either of the computers or the O2 wire I have is faulty.

The O2 sensor wires run to pins # 2 & 3 of the control unit.

Thank you. That explains why pins 2 & 3 are jumpered at the connector.
I guess I'll recheck them with the multimeter. |
