I recently ordered and received a tach from LMC truck to put into my 71. On the back of the tach the wire lugs are not marked and there are no instructions with the tach. I have an HEI ignition on my truck that has a prong marked tach. I do not want to cause possible damage to the tach by hooking a hot where a ground should go. Can any one tell me which prong is which. Thanks, Shawn
