I always hear that the gauge clusters for tach and non tach civics are interchangeable, but is that so for vtec and non vtec. I did a mini-me and I got the d16y8 engine harness and put a blue film in where the vtec light would be. If I put a bulb there will it work. If they are prewired for tachs, are they for vtec also? Or would I have to direct wire the bulb or get a new dash harness?
