Function of inhibitor switch ?

[SVXsnubb]

Hi

Do someone on the net knows what is the other function of the inhibitor switch on transmision without the main task to connect or block the starting circuit depending of the position of the selector and to give information to the TCU.

The function I wonder about is the N and P pos allows to start the engine but also send plus voltage to terminal c10 on the MPFI from the ignition sw. The next is P and N position connect terminal b9 and b10 on MPFI, (motor management), to earth.

Are the functions to keep the idle speed of the engine constant when the seletor for instanse is pulled from N to D or to 3, 2,1 ?

The reason to question is I don´t know what to with thoes cords when
I change to a 5 speed transmition.
