Update:
Today I did the 2G ECU swap, very easy to do. Swapping 5 pins and adding 3. I also found the easiest way to do the ECU rewire was to get a few new pins from Mitsu, my dealer just gave me a few of each size as there are 2 pin sizes and they come with wire already crimped on. Also I did wire the Ignition power pin 82 at the ECU directly to the ignition switch as it was fairly accessible. Check engine light comes on the goes out and we are ready to go. The rest of the rewire will be in the spring when I drop the motor in. Getting pretty close, besides that rewiring all I have left is torque the head on and then do all the timing components. I can't wait.
