<DIV>This would depend on how old your ignition coil is. All new coils are made
for Negative ground systems. So if you have a new coil it should be connected
with the white feed wire to to the positive side of the coil and the white black
wire to the distributor. This would be the same no matter if your car is
positive or negative ground. </DIV>
<DIV> </DIV>
<DIV>The coils have two windings and they will induce from the primary to the
secondary windings when the points open and creating the high voltage spark. If
you connect a new coil up backwards it will still work but the energy will be
considerable reduced. </DIV>
<DIV> </DIV>
<DIV>So no matter what the polarity is on your car the coil should be connected
as if the car was negative ground if you have a coil made anywhere in the last
30 years.</DIV>
