ok so im trying to install the apexi v-afc. gen 1. now where im having problems is wiring up to the ecu harness. i cant seem to get the power pin, ground pin, rpm pin, and throttle pin. anyone have any advice? the harness is the stock civic si pm6 one.

 

which sensor reads the rpms?

 

Find a OBD0 ECU Pinout and it will answer all your questions.

 

thats what i was already looking at. and nvm i already hooked it up and it works great
