Hi every one,

I have recently done an engine swap in 1987 civic and have replaced the carby engine with that of 1999 civic EFI EXI engine with manual transmission.

Now when I am doing the wiring part for the dash and interior, can anyone tell me what is the voltage signal to ECU pin D2 which is for BKSW (Brake Switch). What voltage signal is given to this pin when the brake pedal is pressed?? is it Battery +ive voltage or body earthing or is it continuously given +ive or -ive signal regardless of the position of the brake pedal?? Thanks.

So... any one??

Battery voltage with brake pedal pressed down.

For an OBD2b ECU, the pin is A32.

Thanks Ron... I appreciate it.

By the way... is there also any signal from the clutch pedal to the ECU when the pedal is pressed? if yes then what is the voltage and which wire? I believe this will control the idle???
