I was told I need to keep the F2 relay on the upper harness when fusing the two harnesses together.

It says that the F2 relay provides power to PCM and Instrument Panel, it also says that I can optionally use pin 1 out of F3 (Black/Red) for ignition switched power for PCM. My understanding is if I want to use the 240 instrument panel I will use the F2 relay and wont have to use Pin 1 for power.

If that is the case, do I just need to run the red/black (pic below red arrow) wire into LS PCM for power input? Do I need to do anything with the (black/white) 2 go into the nissan F1 and split into many components I am removing AIT/MAF,etc.

Red is power in correct?

simplified question, If I need to keep the F2 relay for the LS swap, what do I need to do with the black/white red/black wires out of the relay?
