I wanted to carry on with an original thread where Marty (vagparts) found a socket and loom, but because of recent forum silly goings on I can't as it's in a now defunct section
Thread located here in the now closed Open-topic (Old) forum
Anyway,
It seems to have never been answered in that thread, the fact that's it's not simply "plug n play" It does however have our required four wires and they are in the correct positions on the 16 pin OBD2 socket.
I would really have liked to splice in the wiring coming from the 2x2 connector in the fusebox, but once the parcel shelf was off, I couldn't even see the base of the fuse box for the mass or other wiring, let alone strip, splice in and solder.
I asked a friend who has a complete engine and dash loom from a late 1995 Coupe (also has one from a 1993 Coupe too) and he comfirmed that the K and L lines from the ECU connector to the 2x2 connector don't pass through anything else on the way.
That meant I could tap into the wiring at the ECU end.

Means I can now data log on the go and check for codes all without lifting the bonnet. Works a treat too.
