hey my step cousin's alarm keeps going off in her new(used) supra, its a 86' (prod date is april of 86, so im guessing MK2?) i need to know how to disable the stock alarm while keeping her dome lights radio etc..she doesnt like my ghetto ways. i saw an MK3 fix by grounding pin 18 and disconnecting the alarm entirely, but dont know what pin 18 they are referring to. i need help badly and quickly. thanks in advance.
