Craig- You should do the diesel swap with a Isuzu. I saw you posting to the guy. You could do it for a LOT less than him and then your truck would work with 2 wires and a ground strap.

I'd love to, but it's not as simple as the swap you are doing with a D1.  I'd sell my truck and pick up a D1/RRC/Defender if that was the swap I was interested in.  It makes a lot of sense for your truck though.
