Re: $20 Ignitor Replacement/upgrade
Right now I see three configurations:
1) stock configuration - tach is taken from pin 3 of inside the distributor (first pin is +coil, second is -coil);
2) MSD configuration - tach is taken from the old ignitor which also is used as a pickup point for the MSD (the white wire in the pictures is a common node for the MSD, the old ignitor, AND the tach);
3) HEI configuration - tach is taken from the negative of the coil through the 1 kOhm resistor.
