Ignition Cable

NOTE:
Mazda RX7 Service Manuals for this year do not contain a diagram showing spark plug wires from the leading & trailing coil/igniters to the spark plugs.









However, they do show that the Leading Coil/Igniter is next to the battery and the Trailing Coil/Igniter is close to the brake booster.






Furthermore, the locations of the leading and trailing spark plugs are also shown. Firing order is 1-2.
