On the 8hp70 dodge you have to supply external power to ignition + or OBDSTAR DC706 wont read. TCM wants a constant power feed even when switching P004 on and off. The other power needs to switch on and off with the switch.
i have done quite a few and used the wiring diagram on the tool, no issues. That said, i started using a harness with external power and does work better/easier.
