OEM 121 pin connectors
Disclaimer: the following observations could be really wrong, please let me know if you have better information.
See also OEM Connectors - 121 pin
There are two kinds of 121 connectors which look pretty much the same but do not mate together unless you use a grinder to massage them a bit.
This one is used on Asian vehicles - Kia Hyundai etc.
See also Kia Spectra 2005
Note the horizontal line and the lack of double-lines
This one is used on Audi, VW, Mini Cooper.
Note the double-lines:
Use a grinder on the plug. This would probably void your warranty.
Before grinding:
Take the orange rubber piece away while grinding. Grind a bit on the inside.
Re-install the rubber ring.
This way you should be able to use a "German" style plug on a "Asian" style connector.
There is also a 115 pin version - 6 pins are left out (14, 15, 16, 33, 34, 35)
