We planned to do it on our shop car but we sold it. I talked to Innovator's West a bit back about a harmonic balancer they made that had an integrated crank trigger to make the installation a little more simple. I wanted to use LS Coils in our installation. The Casper's harness seems like it would work very well as a patch harness with some modification. However, if I had to do it, it would be a fully unterminated harness going in and I would do a complete rewire. I prefer the Dominator to the HP system because the inputs and outputs are limitless. We are working on a Twin Turbo LSX install right now and have a 68 Mustang coming in for a terminator system next week.
