You don't need a wiring diagram for the plug wires. There should be two coils, with two wire connectors on each coil, the coils should be marked I believe 1&3 and the other 2&4. Just run the spark plug wires from the one and three coil to the one & three cylinders, then do the same with the two & four coil. The cylinder numbers start from where your fan belts are, the closest one to the fan belts (or timing chain) is #1 cylinder, and they follow in sequence 2, 3 & 4.
Hope this helps.
