Run a VTEC wire to where? You could buy an RPM activated switch and make it work to tell the engine to swtich to the big cams at the right time (or a VTEC controller like a V-AFC) but you still have the other issues. For one thing, the fuel maps are all wrong for the engine anyway, and worse, you'll be using the VTEC cams without the VTEC fuel maps. The big side of a set of VTEC cams can ingest more air than any normal street cam could, by matching that with the proper fuel ratio, that's where a VTEC engine gets it's extra power. If you don't have those fuel maps, your ECU will continue to feed it the lower fuel amount than it needs. This will run the engine lean, which may net you some power gains but it can also be very dangerous as a lean engine runs hotter. Your risk detonation and maybe throwing a rod out of the block. A V-AFC could potentially compensate by raising the fuel once you hit the VTEC point, but without a dyno and wideband O2 sensor to tune it, your just basically swinging in the dark. This is ignoring the fact that an automatic non-VTEC D-series ECU will cut the engine short around 1500 rpm short of it's redline, basically slicing off the hightest part of the engine's powerband. You need the right ECU for your engine.
