The 05-06 VTC uses the VTC(+) and power ground, which is different from the 02-04 which has VTC+ and - wiring in the ECU plug.

What would the wiring involve to use an 05-06 VTC setup on an 02-04 KPRO ecu? Grounding the VTC- pin on the ECU to Power ground?

Would it be easier just to swap in an older style VTC solenoid?

Found it out.

RBB solenoid harness wiring only has VTC+

You can wire the RBB solenoid directly into the Kpro by putting VTC+ to VTC+, and Gnd. to VTC- on the kpro ecu

Its not perfect, there is some cam jitter, but buying a PNC VTC solenoid solves that
