Mine is grey as well.
Did you use this same connector back when you were able to check codes?
Any other single connectors close by?
You will need to take a closer look at that wire back to the ECA connector. Must be a break in it somewhere, if you are on the right connector and pin.

I will have to explore where each of those wires go to. They're grounds so it shouldn't be too hard. Trial and error I suppose.

The connector is grey with a green wire that has blue dashes on it. It is the same connector I used before when I was able to pull codes. At that time I used a test light and ran a jumper wire. There are no other similar connectors on that side (passenger side) of the vehicle. The loose connectors on the drivers side are male connectors.

So, connect your neg test lead to ground. Use your pos test lead to probe those ground pins.
Record you readings.

If still an open connection "1", you will have to find the break in the wire.

Yes. There's the rub. For me that's like looking at hieroglyphics. I will study it, but...
I know what grounds look like on the drawing...I think the trick for me will be translating the drawing to what's under the hood.

So I noticed that at pin 48 the wire color is white with a red stripe. How could that be when the self test connector's wire is green with blue dashes. The white with red stripe wire was in the larger test connector. How did that happen? I have no idea. So I reversed them. I now can read codes. I got an 11, and a 10. I'll look that up. Yeah!!!

KOEO Codes = 11
KOER Coeds = 41 HO2S System Lean Bank 1

Honestly, I never switched those. I have no idea who did. I had it to one shop about a year ago and I got the thing back more screwed up then when I took it there. Don't know why they would have done that, if they did.
