Since my tach is way off now ( http://forums.stangnet.com/showthread.php?t=494910 ), I was thinking about ways to get an accurate reading for shifting. I dont want a gigantic tach that mount on my dash cause I dont realy like the way it looks but I was wondering avout shift lights. Can you make them come one at different RPMS for different gears? IE: 5800 in firstm 5600 in second...... How do you adjust them and whats a good kind? I want a small one that I can fit behind my AC vent. I noticed my MSD 6btm has a plug fir a tach or a shift light, I forgot. Can I use that for soemthing?
