I recently switched engine in a 2.5TDI a6 quattro and discovered that the oil temp/level sensor wire was cut off right by the sensor. Now i cant find the wires coming from the plenum chamber. My plan was to run new wires from the connectors in the plenum chamber, but i cant find any wiring diagrams so i dont know where to connect the wires....

It's originally a 2.5TDI a6 quattro from 1998 with AFB engine, but recently switched to a 2005 BAU engine.

If anyone has wiring schematics or a better idea to solve the problem please help
