hey guys found this! DIY knock detection system AKA TVSV LED would the wring work the same with the tvis light or am i just a bit cookoo?? http://celicatech.com/forums/showthread ... post226985
You want to wire the TVIS, and TVSV seperately. They come on at differnt times, and depending how you wire them you change change when they should be on/off.
u can wire up a tvis LED/Light, but a set for on and off would be more difficult. when tvis is on the ecu wire becomes a ground, when its off the wire is nothing, not positive or ground so just wire the + of the light into a 12v source, i used the cigarette lighter, and the - into the tvis wire
i see lol yeah i just thought having a red light for off and green light for on would be kinda cool !! ive already done the tvis led light mod!
