Buzzer and cluster lights with battery connected

Previous to putting new exhaust and oil pan in, didn't have any issue with buzzer or cluster lights. I would always leave the battery disconnected at the negative. Occasionally I would connect the battery and let the jeep run a bit. Since installing new exhaust and oil pan every time I connect the battery the key in ignition buzzer buzzes, blinker indicators are on, and check brake light is on. It doesn't matter if the motor is running or not. Any ideas? I never moved or removed any wiring during oil pan/exhaust install.

I had a buzzer module go wonky once and it caused all kinds of weird electrical stuff until I replaced it. Pull it out and see if the other stuff goes away.

yanked out the buzzer module and issues are gone.
