In my 92 civic i could check the error codes with a small wire in the harness by the ecu...My friend has a 92 prelude h23 and i tried yesterday but i noticed the harness setup is different...how do i do it so i can read the error engine code?? thanks

isn't there a clip (maybe blue, two wires) in your center console under your stereo? close the circuit and the cel should blink the code.

 

there is 2 clips in the middle on the floor board, jump the smaller harness, im not sure what the bigger one is...then you read the code like any other obd I honda.
