Anybody know the procedure to replacing the spark plug wires???

 

There are NO spark plug wires on the xb, just low voltage leads from the computer to the coil pack on top of each plug boot. The wire from the coil pack to the spark plug probably doesn't need servicing, at least for a long time.
Changing plugs in this engine is a breeze.

Well I just got the Nology coil-on-plug conversion kit and don't know how to install.

 

Nology's site doesn't have a Scion-specific install guide yet, but it with invariably look something like this: Nology Coil on Plug Conversion

 

Thanks Dr. Isotope!
