i need to know how to remove and replace the ignition switch on a 1993 tracker boat tx 17, it is a kill swith and it doesn't fire the plugs any more.The switch goes into the throtle body and i have not found any info on on how to remove the switch and replace it.Does anyone have a video or info on how to do this. I could not find a utube on it.I don't want to try removing my throttle body without some idea of how. thank you
