So i got a mechanical boost gauge for my car, didn't really have any issues installing it. It was just a little time consuming. I do have one issues though with the wiring. I decided to use the wires from my clock for my gauge because the clock doesn't work anymore so i thought it was would be a little more practical. The wire colors used for the clock are red, black, orange, and yellow. The wires used for my gauge is red, orange and black. If you already figured, the yellow wire is the odd man out with this i think. I completed the wiring for my gauge using the respected colors. Now the issue: I cant get the gauge to turn off when I take the key out of the ignition. I know i messed up somewhere. I thought the red wire controls that function? If any one knows what im talking about and can help please let me know because this is driving me nuts! Thanks.
