on a standard car, the points connect directly to the coil -ve.

With this kit the connection is broken.

There is a single wire which comes from the dizzy which connects directly to the points (pop your dizzy cap and have a look). This wire goes to the 'from points' on the HEI kit.

Then the HEI kit goes to the coil -ve.

The kit itself switches the coil now and the points are just a low(er) current 'switch' to trigger the HEI.



Remember to run a new wire to your coil negative instead of the old one so that the coil is no longer connected to the points.

EDIT - beat me to it
