The module in the photo is the unit which connects the controls in the back for the stereo. Mine has a sticker on it saying Fujitsu Ten Limited I guess the number on top is part No. 86114-30020 model UU-120 then the ser. No. but mine is identical to your photo. The blue plug should go into the back of the radio/cassette/cd player. I doubt you want to use it as the radio not ging to fit any thing. What are you using the motor in?
