e30 OBD pin-out
I was wondering if you could provide me with the pin-out of the OBD 20-conductor receptacle for my 1989 325iX. I especially need the correct wiring color to pin lay-out . I am unwiring a dealer installed modificaton and the technition pulled some wires off of the OBD receptacle and taped them up. I want to put them back in their proper location.
