im attempting to install a v-tec engagement light to let me know when i am in or out of v-tec. however, i do not know which pin on the ecu goes to the v-tec signal wire. nor do i know what color the wire is (pretty shitty huh). i suppose i could go to a dealership, but if anyone can provide me with an informative answer, well that would kick ***.

 

i could go look, but i dont feel like it...

Solid Blue Wire Comming from ecu i believe, should be same signal wire apexi uses for the VTI light on the vafc.
