You should keep the Ews System that came in your ti not the one from the 325..
Now the green wire you have to cut is In the big round conector on the engine harnes end not the ews unit.. ThiS will enable it .. If you can post some pics it will be great
To see and understand what you mean about the key on the DMe ..
By swapping in your 325 your converting your car to an obd1 .. So all you need is the DMe from that swap . Nothing else. Depending on where it's a non vanos motor u need a red label(402) or if it's a vamos engine u need a red label (413 DMe) __________________  318ti MZK2 |
