Corvair Dual Electronic Ignition

This is what your distributor should look like now. The stock point cover will not fit with this set up. Install the Molex connectors per the instructions in the XR700 kit.

Screw on the Distributor cap and your almost finished. Gather the rest of the ignition parts. Mount the coils, coil switcher and ignition modules to your firewall.

I picked the Bosch Blue coils because I have used them before in VWs with out a problem and they have internal ballast resistance. No ugly sticks next to the coils!
If you use the blue coils get the ones made in Germany or Brazil, pass on the ones from Mexico.

I still do not have my firewall on the plane yet so the rest is from my head on installation.

Route the sensor wires to the distributor. Ty-wrap them together as you would any other wires to the engine. The ignition modules have three wires to hook up. The red goes to the coil + and connects back to a switch in the instrument panel. The yellow goes to the coil - . Black is a dedicated ground. You can use two individual switches (IGN 1/ IGN 2) or a (ON/OFF/ON) switch. Any sensor, coil, module, or electrical wire that fails: just hit the switch for the other ignition.

Make up your coil wires from the extra two cylinder wires in an eight cylinder plug wire kit. They go to the two outside terminals of the coil switcher. Use the real coil wire to go from the center terminal of the switcher to the center terminal of the distributor. Make up the rest of the plug wires for the rest of the cylinders.
