HEI Conversion Done still not starting

You connect the wires on both sides of the ballast together (usually brn & blu) to connect IGN1 & IGN2 circuits. That is because IGN1 gets power only in "run" position and IGN2 is powered only in "crank" position. By combining, you power the ignition in both "run" and "crank" w/ full 12 V, as HEI needs.

Next time, look at the GM 8-pin HEI & coil found in 85-95 trucks (cars to 93, termed "computer" or "small cap" distributor). It is simpler wiring since the module & coil plug together.
