I have an 89 300e (not a california version) and wanted to find out how to read the codes from this car. I did research this and found Arthurs code reader circuit layout, also found the manual for the CS1000 that lists the connections points and indentifies the codes.
Looking under the hood I was able to find the test point just in front of the battery. It is an 8 pin model however, it looks like only pins 1, 6 and 7 have wires going to them.
Is there a different connection point for this car?
Thanks,
Sam
