I have a 1984 300SD with an oil pressure problem. It is not the sender as I replaced that, and I tested the wire to the sender with an ohm meter. Does anyone have a wiring diagram for the instrument cluster pinout on the round connector that plugs into the instrument cluster with the Oil pressure, Water temperature, and Fuel guage. Also have any of you ever replaced the oil pressure guage with an aftermarket VDO guage that will work with the stock sending unit? Thank you for your support.
