&5-78 Tach wiring Please Help!!!
I am putting a 6.0 LS engine in my 73. I have just the tach from a 75-78 (electric) No connetors or wires. Look at the back of the tach there are three push on lugs. One to the left side, one to the right and the last one is below the one to the left. I need to know which one is Possitve which one is Negative, and of course the last one will the tach signal wire. Please Help!!!

Cuda, I tried to find the old control board that I took off of my tach, couldn't locate it. I don't think your tach is going to work without the circuit board on the back of the tach, you could order a new one through any of the Vette supply outlets and I think the terminals are marked on the board.

I have the curcuit board, that is what has the three lugs I discribed and there is no markings on the orginal. I do appreciate your effort. I do find it hard to believe that this information is this hard to come by.
