My problem is that I need a couple of the wiring diagrams from a Bentley
manual for the OBD-2 Golf/Jettas (1996 or newer IIRC). I need the wiring
diagrams that show how the check engine light is wired from the ECU.

I am doing a TiiCo Conversion and want to have a dash mounted check engine
light. My Vgon is wired for a OXY sensor light even though the LED isn't
installed (There is the little black thing in its place, but the wiring in
the cluster is there).The TiiCo ECU is a newer version of the Motronic FI
from the gen 3 VWs. I want to install the LED in its socket (formerly wired
for the OXS) and use it to run the check engine light.
