check engine light won't turn off 98 kouki

You will have a CEL on a 98 S14 until you get a manual ecu. The auto ECU freaks out when it doesnt see an Automatic Transmission. There is also a crank shaft position sensor that goes on top of a manual transmission and I am not sure if you need that one as well and the Manual ECU or just a manual ECU. Gotta hate buying unfinished projects cars.

You are correct, and obd2 car will need the crank angle sensor (CAS) or the computer will flip out. Even with a manual ECU the car will still throw a CEL unless it is wired up correctly with the neutral signal and 5th gear. There are tons of write ups on this OP search google about wiring in a 5spd ECU. By checking the codes you will see what other things may be causing issues. Your best bet is to try to get the previous owners mistakes fixed and go from there. Good luck.
