i have a 1997 honda civic dx 1.6 nonvtec i was thinking of putting a 98 civic ex vtec swap in my dx will the wiring harness be the same?

 

is alil different but you can make it work search around alil, but you can use your harness and just add the wires you need. there is a big write up on it somewhere. and if your not good with wireing and dont mind losing your secondary o2 sensor the just swap the engine harness for an ex one then you will have no trouble just a check engnie light from the missing o2 sensor
