Hi all and thanks for your time.

I drive mazda 323f 2001 2.0 DiTd 101 hp.
I have both diagnostic ports, 17pin under hood and 16 pin under steering wheel.
I am using ELM 327 v2.2 scantool.
So my problem is i can use diagnostic port under hood with ForScan, but not with port under steering wheel.
I've made an adapter for 17 pin. to 16 pin.: B+ to B+, G. to G. and MEN port to 9411-2 (K line) on my scantool.
16 pin obd port have 4 wires: chasiss gnd, signal gnd, B+ and K line.
When i try to use diag software with 16 pin port i cant establish connection to ecu.
So does anyone have some kind of suggestion or solution?
And is MEN port from 17 pin. port and K line port from 16. pin port same wire on ecu or not?
