ok i just bought hatch from some dude and it is wired to obd1 and check engine light is on and i cant figure out why so im convert it pack to obd0 does the 90 honda civic si manifold fit the z6?

 

what is the code for the CEL

 

the light stays on because you have a sensor picking up a problem.
Look under your glove box near the ECU for a blue connector that isn't connected to anything.
Put a jumper in that connector and turn your ignition to ON.
Count the blinks on the CEL... go fix the problem.

Phearable has a nice write-up that shows the connector
