Find the signal for what you think it could be, and ring it through with a multimeter. Shouldn't take more than a few minutes.
If you get stumped let me know, I can come by on the weekend sometime and we'll sort it out in no time.
Thanks so much for the offer man, I may take you up -- but I still think I need anther harness
I still havent found the HFM, and that cut vanos worries me .. thanks for the tip of using ETMs, Ill have to get my meter out and take a go at it
Pics of the entire harness for reference
Close up of the O2 sensor, I re checked the colours again -- this is the only 4 wire plug
