The last one is somewhat hidden. It's on the other side, partially obscured by the black, input
connector block. Remove the screws holding the input connector block to the housing and then
remove the last screw holding the tape deck mechanism.
There is also a plug (not pictured) directly underneath the input connector block. Disconnect the plug
after removing the screws for the block. Next, disconnect the plugs as indicated by the blue arrows
in the picture below. Also, it might help to loosen the square PC board above the plugs by GENTLY
prying back the catching posts as indicated by the purple arrows.
