I think you have bigger problems than that. Are you trying to use a wrx ecu and harness with 25D heads? seems like it if you are asking about the tgv wires. That doesn't work, won't run.
On cars with TGV deletes you can just tuck the plugs somewhere you can't see them or for a cleaner look just snip the plugs off and tape up the wires inside the harness.
