Doing a TDI conversion at the moment with a seat engine.
Having problems wiring the immo box in,
It has two connectors - one goes to the transponder ring, no worries there.
The second is a three pin connector.
I think it loops into the ODB loom, but then loops back out via exactly the same 3 pin brown/tan connector.
This connector seems to have a rogue grn/red wire and connector which doesn't appear to fit anywhere.
It's all CE2, I have the complete donor loom and still cannot plug this in anywhere???
The engine fires then dies so it sems to be an immo problem.
