Where is the second connector/pin for OBD? April 13, 2013, 01:30:03 AM I'm pretty sure I asked something like this long ago, but I can't find the thread. Once again I cannot find the second wire/single pin that is used when attaching a code reader to run KOER tests. Where does the wire come out of? I thought it might be hiding in some wire loom, but I cannot find it. Quote Selected
Where is the second connector/pin for OBD? Reply #1 – April 13, 2013, 10:46:13 AM Mine is on the driver's side by near the brake booster. Both the big 6 pin connector and the 1 pin connector are right next to each other on the same harness. Quote Selected

Where is the second connector/pin for OBD? Reply #3 – April 13, 2013, 03:39:47 PM Hmm I'd check mine but it's at the shop getting some trans issues worked out right now. If I remember correctly both of the plugs come out of the harness in the same spot. The second plug didn't get cut off at some point by accident did it? Quote Selected
Where is the second connector/pin for OBD? Reply #4 – April 13, 2013, 03:46:38 PM I remember a thread about this. Turned out the Self Test input (W/R) was in the six pin connector with the other three wires instead of being a one wire pigtail.The other wires:Tan/LG Fuel pump relay.Y/BK Self Test output.BK/W Signal Return Quote Selected

I remember MANY years ago when I purchased the code reader that there was a separate wire/connector, but I do not see anything like it now. I seem to have 5 wires in the larger connector?

Is that cable harness from something newer than 88? Quote Selected
Where is the second connector/pin for OBD? Reply #7 – April 13, 2013, 04:20:00 PM I screwed up!! It is the Self Test Input wire W/R that is the single wire connector. Quote Selected
Where is the second connector/pin for OBD? Reply #8 – April 13, 2013, 04:45:32 PM I found this connector arrangement that I saved about a year ago.It is supposed to be the "International" version of the connector and shows the STI (self test input) in the 6 pin connector.Do you know if your car was built for export?

Where is the second connector/pin for OBD? Reply #10 – April 13, 2013, 07:50:33 PM There is nothing in there. I'm pretty sure I used to connect a separate wire to the code reader long ago, but I don't see anything of the sort now. The Brown and Yellow/Black both go to the same pin. The rest are obvious where they go I think. It looks like I have fuel pump, signal return, self test out, and whatever the pin is opposite the fuel pump. Quote Selected
Where is the second connector/pin for OBD? Reply #11 – April 30, 2013, 02:40:15 PM Looking for this answer too. I just tried to read the codes today with a cheap scanner and had no single wire to connect. Quote Selected

Where is the second connector/pin for OBD? Reply #13 – April 30, 2013, 11:41:49 PM The Y/BK and the Tan wire in the same connector pin is correct. This is Self Test Out and the tan wire goes to the check engine light.The White/Red wire is the Self Test In. Unplug it from the 6 pin connector and hook it to the single wire on the code reader.
