i think he's right ^^ but if you went from KA manual to SR manual i'm pretty sure everything would lline up, R240NA would know this, you should try summoning him. but i went from AT to MT and i dont' have a worknig speed sensor right now, just a tachometer. but it's normal to have extra plugs, the FSM would help you in this situation.
props for choosing your car over drinking, i'm neglectful in that aspect
i'm at work right now with a horrible hangover
