a/f ratio gauge help
I installed an a/f ratio gauge and when I start the car it doesn't light up... After driving for a while the gauge comes on only when I'm on the gas and the second I let off, the gauge lights shut off.... I have this wired into the radio ignition wire and radio ground. The signal wire I spliced into is the black wire.
