keep the turbo timer at the same angle as the stereo or else it will look funny. What I did was yank out the clock, then look at the two holes where the clock went into, stick the long end of a normalsized allen wrench into the hole closest to passengers side (drivers side is left alone because the center panel wont go back in otherwise) now get superglue(too much will make your panel and turbo timer fade white, so be careful.)cut out a piece of plexiglass or hard plastic the size of the turbo timer. glue it to the allen wrench and put a fine bead of glue down the edge of glass that contacts your panel. then use velcro with sticky on both sides and voila!!
Also if you havent wired up the turbo timer(japanese instructions maybe) If you have an aftermarket cd player and know your wiring harness, you can tap in to most all needed wires there.
