Im trying to find x26 connector on my 1987 300D, but i cannot find it. Im tackling the job with the rpm guage not working, and i was following some guys thread about checking AC voltage at the diagnostic box, right at the battery (pin 2 - positive lead, ground - neg lead) I dint get anything, so im trying to find out if the wires are damaged from the x26 connector to diagnostic connector.
It should be under the fuse box, but there are only 2 connectors with only 2 or 1 wire coming in and going out (x26 had to have 12 wires). Please help...
