oh yes the vtec light.....its simple actually....first take out the meter....clean one area...remove the black paint from one of the ovals.....in my case used thinner..on coton bud..then go to any printing wala....with vtec name picture and tell him to print it out in light yellow paper.....according to the size of the oval but u have to cut a bigger piece of paper more that the oval so that it could be glued....
then you would need 2 wires one long one short....one bulb holder and one bulb....attatch the negative end of the bulb wire to the rpm wire...and attatch the positive end of the vire to the vtec soleniod in the ecu...and voila u have a vtec light...
ps this light doesnt work on idle revving...when the car is moving and u floor it after 3400 rpm the vtec light comes on....its very help ful...u always know when ur vtec is working or not...and helps in feul economy too...because vtec light off means car is using less feul...and viceversa..
i hope it helps...for further details pm me ill help u out...
