I refined the off board adapter a TON but didn't take any pics.. I basically ditched the whole harness and just ran a few wires from the pcm pins to the OBD port.

Battery +
IGN +
CLASS 2 communication
Then like 4 grounds.

I used Tech-2 power supply to power the tech-2.

The 12v batter powers the PCM.. it dialed in at 12.4 volts.
