With the addition on the small wire link shown in the other pictures, the 16-pin ODB port in the car should work 100% for all diagnostics, emission testing included.
Ensure the 20-pin cap is on and go for the test. At least, that's how it should work.
If the emission testing station is trying to connect via the 16-pin when the 20-pin cap is off (open) it will fail.
