my friend just bought a obd1 LS motor and he wants to swap it into a 96 ek, now will the stock LS harness plug in and work or does he have to use his cx harness?

 

Your gonna have to do some wiring. I would stick with the cx harness. The injector clips are different and the dizzy is diff. IDK what else is i try not to **** with obd2

 

EK has 1 piece harness. Tegs have 2 piece harnesses that "break" at the shock tower. Its only an LS so just use the Civic harness.

EDIT: As posted above, yes you will need to convert a couple plugs or just run an obd2 dizzy. You also need a jumper harness if the ECU is OBD1.

 

I learn something new everyday lol
