The Joe Bialy '93-'94 Distributor HEI Module Mod (aka blown ignitor fix)

Parts/tools needed:
-HEI module 4-pin
-4 lengths of wire about 3 feet each (trim to fit...some will only end up being a few inches)
-wire stripper/crimper
-wire "spade" type connectors that will fit the HEI module conectors. These should be "hooded"/insulated type
-razor blade or scalpel to strip insulation on wires you don't cut
-electrical tape, heat shrink tubing or paint on insulation
-30 watt soldering iron
-silver solder

Procedure:
Use this picture as the wiring diagram reference: http://img150.exs.cx/my.php?loc=img1...e=hei018cc.gif

-remove spark plug wires off disty cap (label them)
-Remove disty cap
-remove rotor (remember it's orientation)
-you will now see this: http://img150.exs.cx/my.php?loc=img1...ge=hei29wi.jpg
-remove the strap so it looks like this: http://img150.exs.cx/my.php?loc=img1...ge=hei36yk.jpg
-reinstall the rotor
-reinstall the disty cap
-cut the wire closest to the firewall on the 6-pin harness. Leave a lot of wire on the disty side in case you need to reverse the mod.
-strip then solder a wire to the ECU side (not the side still connected to the disty) of the wire that you just cut. Connect that wire to the "G" connector on the HEI module. Insulate soldered splice point.
-tap (do not cut) and solder into the wire closest to the firewall on the 3 wire connector. That wire should go to the "B" connector on the HEI module. Insulate soldered splice point.
-tap (do not cut) and solder into the wire closest to the radiator on the 3 wire connector. That wire should go to the "C" connector on the HEI module. Insulate soldered splice point.
-connect a wire to the "W" connector on the HEI module, then connect that wire to the "GND" on the HEI module.
-then connect the wire on the "W" and "GND" to the negagive battery lead or any grounding point on the chassis
-mount the HEI module somewhere secure

That's it. You are done.

If you are using a more complicated setup such as one utilizing an external coil, then you'll have to hook up the resistor, etc. For a simple '93-'94 disty ignitor fix, this is all you have to do. The '95-'97 wiring is similar but still in the testing phase
