It might be worth asking some of the Honda swap guys. Some make their own conversion harnesses, and may be able to set up one for you if they know what is required. For example,
Rywire : .
Just make sure they know what exactly you are asking for and make sure you know exactly what they are going to provide. They generally make stuff to put bigger engines in smaller cars (e.g., B18C into a late-80s Civic or CRX), so "convert VX to fed" may not mean much to them.
