my dash has been through hell of reverse glow gauges, speed hut gauges, piece of **** gauges, i got tired of looking at glue residue so i put a black vinyl over it and bought those pieces.. with the vinyl it didnt light up so i put LED's into it.. as for AEM gauge.. it has no backlight so it doesnt light up.. i just need to see the vaccuum and its only going to go up to 6lbs right now so
