it bolts right up to another sc....or u can just take the ignition and steering wheel and swap it out wit yours(i think that would be easier)......i taught i needed a new ignition and the only way gagels would sell it is if i bought the whole thing...but it ended up being my alarm that was messed up....so inturn this it why this is for sale.....the only thing you would need is a 98+ lexus airbag......
