in the instructions it says I need to install 3 wires.
red=power
black=ground

then it says to install either the
yellow or white wire which is either a pressure sensor or air flow signal.

it shows where I should install the yellow or white wire but not which one I need to use...

any help appreciated.

 

nevermind, i figured it out.

 

Why in hell are you installing an FCD into your car when you have a Power FC???

 

Ok Trying To Hook Up My Fcd And My Split Second, I Had A Wiring Diagram But It Seems To Be Incorrect. I Need To Know Which Pin On The Ecu Is For The Air/pressure Sensor Wire, Tach Signal, And At The Diagonostic Box Under The Hood, It Says Tac, But There Is No Pin For It. Please Dont Flame, Car Is Taken Apart In The Drive Way And Its About To Rain I Think, Any Help Would Be Appreciated,

 

see pg. Z-32 and Z-36 of the Wiring Diagram (pg 35 & 39) of the Wiring PDF available here https://www.rx7club.com/3rd-generation-specific-1993-2002-16/94-fsms-available-download-449950/ )


Air/Pressure Sensor (MAP Sensor)
Pin 1O (the number one then the letter "O")


Tach Signal: I didn't find an ECU pin labeled 'tachometer', but there are two ECU pins that connect to the speedo/tach in the gauge cluster, pins 1N and 2B. According to the diagram I've got, there's no connection at the "TAC" pin of the diagnostic box. Try the IG- pin on that same datalink connector, because it also connects to pin 2B on the ECU.


Good luck,
