Plug off or tee into it as necessary and don't forget the 4x4 line that has corrugated line around it. As for wiring: only thing needed is to extend the iac pig tail, and extend the iat sesnor to monitor manifold boost temps instead of iats.

Esof 4hi can engage during moving so it's not governed entirely by the PCM. 4lo has to be due to when it is able to actuate the t case. I have a schematic if anyone needs it.

As stated above lol. So yes anyone with a L PCM can run 4hi with no issues.
