just one grey one left.. red and black makes the lights come on.
Andy
it goes to the lambda sensor mate,it works by sensing the switching of the lambda voltage

thought so, whats the easiest way to get there, and which wire do i splice into as there are 2 from memory.
Andy
should be spliced in to the signal wire. that should go upto the ecu. so its easier to splice it in there.

guess what the wire at the top was!
ran a wire over the dash out the door under the bonnet for now as a test.
it seems to work, tho anything over 2.5k RPM and its too lean apparently.
what readings am i ment to be getting etc.

thats the guage
think it should run in the optimal range all the time. did it not have instructions at all. never fitted one myself.

didnt check.. :P
opened up the loom before it enters the scuttle panel then stripped the mauve one then wrapped the signal lead round it and it worked!
