T4 2.5 ACU Relay box missing module / connector?

[TransporterDaz]

Hi guys,

I wonder if anyone with a 2.5 petrol T4 could help me with this.

I bought a Vag-Com generic cable and installed VCDS to connect to the ECU in my '94 2.5 petrol T4. VCDS could not find the ECU. On tracing the white OBD1 connector it seems to be connected to nothing in the relay / fuse box! Can anyone enlighten me as to what should be here? It seems like there should be some sort of module?

The white OBD1 connector cable (yellow and grey / white) is connected behind where I have circled in red.


Thanks in advance,

Darren.

The amount of relays/modules vary depending upon what options are installed.
I find VW electrics bamboozling..........and I'm trained in electronics!

Unfortunately, I sold my T4 and can't go out and take a look anymore.......but that was a 2004 model and may have been a bit different.
