HEI distributor

I had completely rewired the 88 d250 to get rid of the TBI.....I used a 30 amp circuit breaker that provides the power to the coil.. power has to be provided during the start and run circuit.....outside of that the red wire to the plus side of the coil and black to negative side of the coil.....You should use an E coil also...and you do not use any ballast resistor..the coil must see the full 12 volts

I think I got mine from Skip White...but they are all the same...
