okay i got the pic off ecu-man......thankyou
only prob i have is i need a pinout like the meaning to each wire as no where clearly does it say rpm. vss iam assuming is vechile speed sensor, also that pinout ecu-man does not have the wire colours.

i think iam good now boys.
i got a ek4 pinout and matched it with the picture in the apexi manual to find my terminology.
ICM- RPM
PG1- grnd
IGP1- ignition power
VBU- power
VSS- vechile speed sensor

for once i wish honda followed nissan with its ecu terminolgy.:thumbdwn:

you got it right

never go by the colour, always pin number.

colours can and do change

all done and all working a-ok
thanks for the help esp. ecu-man
only question is my dash speedo on dead 100km/h rsm reads 94km/h, however i tapped into the ecu so how can they be getting conflicting speeds as both are comming off same wire?

the dash speedo is always off an never accurate.
well most cars are off, some cars come close, some cars are dead spot on.
lol.
