Since 1999, you can install either the PC3/5 w/bung]. The telemetry is the same. So, if an '06 was the year, then yes, it is fuel injected and use the same injector wires.
Now if they are an 8 injector with a 4 wire PC, then no, I do not think you will have the lower or upper working if you use one set of wires one either 4 injectors. Meaning, you will jet the lower rpm with the injectors in the throttle body. But say the top end injectors are on the air cleaner area or at the top of the throttle body, then you could set those 4 wires and wait for the mid to WOT to change transition from low to high. Something like that might work I do believe.
