Off the top of my head, if it's an aftermarket tach, I know for sure red is +, black is -, and I'm 99% sure green is for the tach pickup. White should be for lights. Not sure on the aftermarket shift light though.

Good luck.

The color's I have are red- white- blue- black-green

Just guessing here but is it
red-12 volt's
black -ground
green-tach lead
I am sure blue or white must be light but then what is the other wire for??????
