Car is a 98 5 speed manual. I pulled out the f23a5 non vtec and swapped in a f23a1. picked up the correct ecu, even tho the car will run and drive with the non vtec ecu. everything works exactly as it should besides my temp gauge. after doing a little bit of digging and reading through manuals and diagrams online, I found out that the ecu reads the water temp from different signals varying on the year (98-99, 00-02). now im assuming that I have a 00-02 ecu which would explain why it wont read on my gauge cluster. has anyone made this work before or know what wiring I need to change/ do to make it work without trying to find a gauge cluster from 00-02? any helps appreciated
