12v neg ground system, ignition (+) to (+) side of coil and the (-) side of coil to the distributor. If the coil is getting hot there is most likely more voltage (power, wattage) going to it than it was designed for. Either reduce the input (add resistor) or change the coil. The Bosch Blue coil if often recommended (see #5 above). Have you checked the resistance of your existing coil?

Note: Yep, see Babba post #8!
