Ladinsay, I'd have to see a pic of yours to know what you are in for, but panda should have it easy.
The red wire is the coil wire.
The green w/red stripe is the hot (TWO wires from the tach go to it)
and the brown is the ground. Check the wiring diagram that came with the tach (assuming you got the DS one I did) and I think you should have it.
