I have a 2016 XLT 302a and I can't find the test port behind the OBD connector. I've taken down the plastic shroud and crawled underneath the steering column and I don't see any loose connectors. I've looked over and over again and just don't see anything. Is there a trick to finding it or might not all 2015 - 2017's have the test port?

you sure there isn't a small white plug tight behind the ODB2 plug ?

This is directly underneath the OBD plug. Nothing there.

Above the OBD plug.

well I don't see it either.
Did you look behind the rear passenger seat for a plug end landed in a holder, above the jack ?
larger black end that fits the tcu ?

Looks like whatever that blue plug is using it. Did you add anything aftermarket?

I unplugged the harness from the blue plug earlier. That's not it. Nothing aftermarket added. I'm stumped. May need to find a different way to connect the TCU.
