Power PCM when battery cut off switch is off
Power PCM when battery cut off switch is off Long story short I would like to run my PCM memory and radio memory straight to the battery. I know the radio will work out ok.
Question is which pins do I need to power directly from the PCM. I see blu 20 and 57 are battery power. So do I need to power both? Will the car still shut off when the switch is shut off?
Just a thought because the cars sits and takes a little driving to start shifting right under boost.
I searched but never found any real answers.

Makes sense. Didn't even think of that. I'm not worried about Nhra because I'll be able to change it back to stock by swapping wires.
I just want to make sure I need to power both pin 57 and 20 to make it work.
