Timmer,
You do have a problem for sure. Years ago the manufactures of some products used little tags on the wires so all the wires could be the same color. Then when they were removed and people cut the wiring you are left with your problem. My only suggestion would be to see if you can figure out the mfg. and contact them or take the tack apart and get pics. and send to Sun or Stuart Warner and maybe they can tell you how to hook it up. I would not chance hooking it up because I did that years ago based on the tags being gone and fryed my tach.
Good Luck
Paul
