[70nova]

Hello,
I have a vdo tach that is a few years old,but has never been used. My question is that it has red,black,green,blue and white wires. Can anyone tell me were the blue and white wires go? They can not both be for light can they?
Thanks Steve.

On my Sunpro tach, the wiring is:

Red: Switched Power
Black: Ground
Green: Tach Lead
White: Dash Lighting Circuit

I don't have a blue wire, but maybe that will help?

Good luck,
Ryan
