You didn't tell us what year your Westy is....   On my 85, there's a green
wire that attaches to the oxygen sensor.  It runs to pin 5 on the ECU.

I share your pain... I have a wire hanging down as well that I'll research
one of these days.    :o)  I have no idea where it connects.  All the vital
stuff is wired up.
