Hi Guys, Due to one of oil pressure gauge dying I went out and brought a new saas boost gauge and oil pressure gauge. I have mounted them above the ICC and they light up and work correctly. the issue is there is a button on the back of the gauge that changes the LED colour of the gauge face and that doesn't change from the factory bright white light. when I plug the gauge harness directly to the positive/battery/lighting cables straight to the battery it works and changes to blue,red,green etc....any ideas why the cig lighter wont do it ? and where I can wire it up correctly?
