So I just installed a prosport boost gauge from the alta kit. I innitially had a wire disconnected [switched 12v] but it was ttaped into it and when I locked the doors I got a single toned beep. After reconnecting my switch wire the gauge works perfect the beep whent away 2hen locking the doors. Except it did it one time today and once yesterday. Maybe one out of 30 times locking the door. But it is just a pretty loud single toned beep that sounds like its coming from under the brake booster. Anybody have any thoughts.

Innitially I thought I caused a short that happened to trigger it but the fact that it randomly occurs now has me stumped and I never heard it before when I would lock my doors
