Urgent help with group buy gauges
 

gents
Bought 3 gauges all ok except the boost won't work lights up goes through the opening ceremony then needle stays at the bottom ..... Wired live and ground straight to battery and orange to the stereo ign so signals are good cut into the inlet manifold again where I had a mechanical gauge.... I have since bought another sensor as I thought it must be faulty fitted it today not a bit difference... I have no more ideas can anyone shed a bit light

try linking across to another gauge 2 c if your wiring is at fault....i am assuming all your gauges are to-gether
