If you can't do the wiring for this swap, you shouldn't be swapping engines at all. It would be more trouble than it's worth to try to use some wiring kit for this swap. It's one of the easiest out there:
- VTEC is already wired, plug and play
- One wire for the IAB back to the ECU
- One wire for the knock sensor back to the ECU
- Lengthen the IAT sensor wire
That's it (I'm pretty sure, it's been awhile). What "controller box" are you talking about?
