my car 1989 crx si or zc , the motor that will go in is from a 1990 civic b16a.
i hav got the hasports mounts ,
but the writing some pll tell me i only need to add 3 extra wires. Knock sensor, Vtec solenoid and Vtec oil pressure switch.this is fine

i know the civic loom (wire coming from engine) will fit in the ecu but i need to know will the writing loom form my crx fit in the civic ecu or i need to modify
the writing?
thanks

 

zc wiring is different, from the dizzy part, the zc dizzy has 5 wires, the b16a has 7! i guess thats the only different

 

so just cut the 2 extra wire?

 

any help?
