Hey,

So basically, what I did was, used the search feature and went through EVERY VTEC light thread and i'm still such an a$$ I didn't get it. So I took a picture of my ECU's wires and I want to know which wire to connect the positive wire to? And I just splice it a little and knot it there to the vtec wire, right? And do I really need a resistor on the negative terminal? I have a green LED that is pretty small and it's normal, not very bright.

My car's a 90 Civic with a JDM D15B VTEC.

Looking at this; http://www.innovatemotorsports.com/resources/1996_1998_Honda_Civic.php

I think the vtec wire for me would be the 2nd one from right. Am I correct?

Here's the picture;




Thanks guys

I tried connecting the positive wire to the green wire already cut in the top picture but it turns on as soon as i turn on the ignition and stays on :/ HELP.

this is pointless do you really need to know when vtec engages? can you not tell?, it hits at the same rpm everytime EVERYTIME its not like it changes
