I was trying to get back to my M.A.P sensor on my 2.2 2002 cavalier ans I noticed a litte box with wires coming out of it. One wire was connected to my battery, another one was grounded to my engine and the other one was just hanging around not connected at all. The little box says BEULER on the top. What could this be?????
beuler....beuler......bueler
maybe there was somethign else hooked up to the car before u owned it? In my 2000 I don't have any wires other then the Pos and NEG battery cables hooked up.
Maybe u can take a pic?
