Ok mate, will do at the weekend, if it looks like ive forgotten you send me a PM on www.vauxsport.com and remind me, as ive got a lousy memory.

theres a 3 pin connector on the bulkhead, on the side that goes down to the sensor itself you got 2 white wires and 1 black. mine is tapped into the black. which translates to the brown with blue trace on the other half (the car loom side) of the connector

i only know this as i intend to disconnect it. its just useless flashing lights when used with the stock lambda sensor. the sensor only reads voltages for close to "stoich", and not the voltages for 12.whatever AFR on boost. so basically the guage wont show you anything useful regards the safety of your engine.

my narrow band gague was good, as i knew i had a fuel problem on boost as it wasn't reading full rich just over stoich on boost where as before it was reading full rich. so they do work in some sense
