DamoC Posted June 3, 2013 Author Share Posted June 3, 2013 Right... The wires in which my current boost gauge are tied into.. There is only two as its a manual.. So it's a black (earth) and a green (lights) so when my lights come on so does the backing light of the gauge! My new gauge how ever has two wires, and a third wire including some "piping" which is the same as the current gauge, I did not connect this up.. (Might be why it didn't work?) I have only two wires on the new gauge which are usable? But I do have the black, red, white I think and grey? Not 100% sure though! So I thought I would do the obvious, and swap the live for the live and earth for earth and it would All light up and that would be the end of it.. Oh boy was I wrong! Done that.. Even changed wires around and still nothing.. Any other advice? Quote Link to post Share on other sites
