Components with the new M4 type connectors are not interchangeable with the old style. If replacement of any component is necessary, install complete set with all connections of the same type

Fig. 16 Ignition Cable Resistance Test:

Coil Wire
With radio 2000 +/- 800 ohms
Without radio 0 ohms

Spark plug wires
With radio 6000 +/- 1400 ohms
Without radio 1000 +/- 400 ohms

If resistance is not within specification, check individual components.
