sc_toy, 98 or OLDER ES300 6-disc changers will plug right up to the harness and the head-unit will control it perfectly. Not too sure on 99 or newer changers. Regards Nick T

AppleJack, Take your rebuilt starter to your local pepboys, advanced auto, trak auto etc. and have them bench test the starter. Most offer this service for free. Do not crank it while someone is holding the starter, very bad idea. The starter will put out so much torque it will probably fly all over the place. I would also advise against trying to crank it with the top-end uninstalled. More risk then it's worth. Regards Nick T

SC300 changed over to the same size brakes as the SC400 sometime in 96 or 97 so your 98 SC300 rotors will fit the 97 SC400
