Tach Wiring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have bought a tach from Cheyenne Super Man and I have tach wiring question. On the stock wiring there is two wires that come off the positive side of the tach. I understand that on an HEI ignition there is a tach place and a 12v location for the ignition. But the ignition is already plugged into the distributor there. So where does the second wire go? The on the stock wiring there is a ground. It seems that this would go to the coil but in this case does it get grounded to anywhere or can I ground it to the fuse panel. A little advise would be great. Thanks
