dont know the specific model number, but the old school sun tachs used to need a box(transmitter) that went along with the tach, tach went to the box, box went to coil. if i remember correct its about the size of an msd box, but a bit smaller. i think all they are is the workings/electronics that come in the newer tachs, but they used a seperate box to hold them, likely because the old tech stuff just took up more space. kind of like how computers went from taking up a room to what they are now.
is it one of the larger chrome, glass faced types you see in the old drag photos? i think they are very cool, from a nostalgia point, but you have to have the transmitter, or it wont work. i'll bet you can find a transmitter for it still, on ebay or something.
good luck with it
