"Jumping" 30 Pin PSA Diagnostic Plugs

[addo]

I - as some others - experience dialogue issues at times with the faux Lexia, especially when using the 30-16 adaptor.

If I were to make up simple jumper wires to go from the car's socket to the 16 pin Lexia plug in hope of better connectivity, exactly how many do I need to get communication initiated? B+, B-, shielding and the specific pin sought?

Or, do I need initial dialogue with more elements of the car, to satisfy Lexia?

Hi Addo

I use the 30 pin to 25 pin adaptor in preference to the 16 pin one.
Can bell out both sorts for connections if you need it.
