I bought the Sport-Comp DPSS Gauge, Level 2 and im just curious as to where the green wire would go for my 2002 ls1.. the green wire goes to the ignition tach output which i don't have cause i don't have an ignition box or it goes on the - of the coil.. how would i go about doing that??

PLUS this shift light/tach has a launch light which when the car is not in motion it will light up when im within like +/- 100rpm of my desired launch rpm and if it goes over it will flash...
here is the diagram

im guessing for the launch light i need to just hook it to my clutch pedal...

how would i do that???

PLEASE HELP!!!
