If anyone here have problems with their AEM UEGO gauge making a high pitched ringing sound with the headunit on, make sure that you're not tapping the radio harness for power/ground. This thing needs its own power and ground. I've tried only using the radio for power and the chassis for ground, but it would still make that annoying sound. Problem was solved by using a fuse tap from a 12v ignition source and a chassis ground.
