Ok, so I am guessing you have not tried connecting the 626 with the Mazda software along with the 17-pin adapter; Try it first using Mazda software, since the OBDII software only works with the OBDII 16-pin port under dash. You might also try to use the Ford software under USA tab and if available in your DS708, EU Ford under Europe tab with 17-pin adapter; under either one of these software you will find when choosing the manually vehicle selection, the selection for the 626.
FYI, under Mazda or Ford software you will find under the manual vehicle selection (3rd option when starting software) the option for 626/626 wagon/Tesltar along with option for the 1.8L, 2.0L, 2.5L engines and which after selecting type of engine(s), the appropriate manufacturing years can be selected. Hope this helps and good luck.
