Pin 1,2, 4 are ground.
pin 3, 5, 6, 92, are Relay switched 12V.
pin 67 ( Orange Brn ),68 ( orange blk ), and 86 ( Gray White ) are the data pins.
that is all from a 2008 GTI.

There is no need for the K-line, although I wired mine up anyway.

Daz were you able to write using the bench harness without an immo defeat? |

If it's on the bench then BDM it.
You can't write it without immo defeat, as it will reject security access.

What PRJ said. I can connect, but not write as security access blocks it. With the immo-off, I can read and write without an issue, but at that point I'd rather BDM as it takes half the time. The PITA is opening those things. |
