its similar to auto meter, so this would be the wire setup
red : power
white : ignition
black : ground
green : rpm sensor

Hmm, let me try.

Red = power
Black= ground
White = Dash light power source
Green = Ignition source

Ultimately you should call Summit and ask. They are pretty good at helping out and since it is one of their tachs they should have the information or help you find it.

Summit # 1-800-230-3030
