Yes, 200HP 97 Johnson. The harness is hooked up, but I guess when I pulled the old guage the buzzer mechanism came loose before I could see where they attached. I attached the buzzer/beeper straight to the battery and it works. It is the black disc with only a small diameter red and black wire coming out. On the back of the new gauge there are to small holes that have an "I" and "S" are they supposed to push into there?
